The root system is the vegetative organ of crops and is a nutrient source for crop growth. It plays a very important role in crop growth and yield formation. The roots of crops can be compared to the human stomach.
Because of the importance of the root system, many companies have seized this big selling point. Barrel rooting agent is a kind of functional fertilizer fertilizer product that has been rapidly developed in recent years. The main function is to promote plant growth regulators , such as Indoleacetic acid, indolebutyric acid, naphthaleneacetic acid, sodium nitrophenolate, amine fresh ester, etc. In addition, some of the trace elements in the product, or chitin, alginic acid, amino acids, humic acid, etc. Organic nutrients, or various complex microorganisms. Reasonable use not only promotes root growth, enhances root absorption capacity, regulates plant growth, but also supplements some soil nutrients and regulates soil.
The effect of barrel rooting agent is obvious, the cost is low, and the profit is considerable. It is also a hot spot for agricultural resource distributors to promote. However, as a product whose plant growth regulator plays a major role, the requirements for the use of technology are relatively higher, and the requirements for dosage, applicable period, and applicable types are relatively strict. Many vegetable farmers lack understanding of this aspect, and the use of rooting agents has been planted a lot, and they have suffered a lot.
Rooting agent has good rooting effect and quick effect. Many vegetable farmers very much recognize the role of rooting agent. Whether it is smashing, watering or rooting, there will be some rooting agent in case of nothing, and the abuse is very prominent, which seriously affects the normal growth of vegetables. In recent years, the premature aging of vegetables with high incidence has a great relationship with the abuse of rooting agents. The problems of “only roots, no fruit†are also inseparable from rooting agents.
Typical case 1: Continuous use of rooting agent alone leads to premature aging of vegetables
Continuous use of rooting agents alone, especially during the low temperature season in winter, can lead to serious consequences. Although the effect is obvious in the short-term after using the rooting agent, the rooting agent contains no or little inorganic nutrients. The continuous use of soil nutrient supply is not supplemented, and the nutrients available for roots are less. Even if the root system temporarily increases, the nutrient supply is insufficient. The problem of premature aging of vegetables will soon appear, especially in winter, a large number of eggplant, sweet pepper, cucumber, etc., which show that the leaves are yellow, thin and small, the fruit grows slowly, the yield is reduced, and the quality is degraded. Many vegetable farmers do not understand how it is going, watching the growth is not good, and increasing the amount of rooting agent. As a result, the growth of vegetables is getting weaker and weaker, and eventually the garden is changed early, and the loss is huge.
When the price of vegetables is low, the effect of premature aging on the benefits is not particularly large, but the high incidence of premature aging is the winter and spring season. When the price of vegetables is the best, the premature aging caused by the abuse of rooting agents needs special vigilance.
Then, where is the focus of prevention of premature aging? Zhao Xianliang, a vegetable farmer in Jitai Town, Shouguang City, has been planting a large eggplant. His eggplant has never experienced premature aging, high yield, good quality, and the neighbors are very admired, and he rarely The use of rooting agents protects the roots from other aspects.
The first is to cover and remove the mulch film in a timely manner, and cultivate the strong root system.
From colonization to planting, a large vegetable grows for eight or nine months, and autumn delays take four or five months. The growing season is long and requires a strong root support. Covering the film, multiple watering and top dressing, walking back and forth, etc., will make the surface layer of the greenhouse soil severe, the permeability is reduced, affecting the root activity, causing the root system to weaken. It is recommended that vegetable growers start from vegetable colonization, cover the mulch in the evening, combine cultivating and cultivating to cultivate strong roots; after the temperature rises in spring, the mulch should be removed early, the cultivating and raking should be done, the soil surface layer should be broken, and the soil permeability should be improved. When the soil conditions are good, the root activity is naturally strong, and the rooting agent is not needed, and the plants do not decay early.
The second is to rationally water the water and adjust the proportion of topdressing.
Watering is the most important part of farming operations, and its role is irreplaceable. Vegetable watering should be combined with water. The large water is poured, which can expand the range of root activity, which is beneficial to improve the root absorption capacity; small water can meet the normal growth needs of vegetables, reduce the damage to the soil, and ensure the stability of a large number of shallow roots. In the middle and late stages of vegetable growth, the topdressing should be properly adjusted to increase the proportion of nitrogen fertilizer, maintain the balance between vegetative growth and reproductive growth, and avoid premature aging caused by excessive reproductive growth. If the growth of vegetables is relatively normal, it can be applied to balanced fertilizers; if the eggplant grows weakly, it can be applied with high-nitrogen flushing, such as 30-10-10, 5-8 kg per mu.
For the phenomenon of premature aging such as yellow leaves, it is necessary to "up and down". The upper leaf surface sprays 600 times of cytokinin, 500 times of nucleotide foliar fertilizer , and 300 times of total nutrient foliar fertilizer to alleviate leaf yellowing; the root is combined with nutrient-type fertilization, combined with chitin and alginic acid. The rooting agent products, such as the sea spirit functional fertilizer, are widely used. This functional fertilizer not only promotes rapid rooting, but also enhances the root absorption capacity. If necessary, it should also reduce the retention of fruit, pruning and sowing, and reduce the plant. Burden, increase the supply of nutrients in the roots, and promote the rapid and robust plant growth.
Typical case 2: The fully water-soluble fertilizer is supplemented with rooting agent, and the vegetable “only grows roots, does not open fruitâ€
The fully water-soluble fertilizer combined with rooting agent has become the standard configuration for many vegetable farmers to water, which can supplement the nutrients needed for plant growth, promote rooting and enhance root absorption.
Perfect match, the effect of the lever. Is this really the case?
No, when the growth of the vegetables is normal, the nutrient-type fertilization can meet the growth needs of the vegetables. The rooting agent is actually unnecessary. The use of the plant growth regulator is excessive, and the hormone balance in the vegetables is Breaking, it is more prone to various problems. Some time ago, the reporter encountered a typical example of continuous production of water-soluble fertilizers and rooting agents. A vegetable farmer in Xidanhe Village, Daotian Township, Shouguang City, took the tomatoes and reflected that the tomatoes he planted only "long roots, no Open the fruit, pull out by hand and watch the root group can have a small basin, but the tomato fruit is very slow, the yield is not high. And his neighbors don't look too long, there are not many roots. After pulling out, the small bowl is big, the tomatoes are growing well, and the output is higher than him. It is really strange. Obviously, only the long roots and the unopened fruit are the manifestations of uncoordinated growth. The nutrients produced by the leaves are more transferred to the roots, and the nutrients obtained by the fruits are less, and this abnormal phenomenon occurs.
What is going on here? This is starting from the current recipe for fertilization. The fully water-soluble fertilizer is known for its fast dissolution and good effect, but the components of the fully water-soluble fertilizer are still mainly urea, potassium nitrate, potassium dihydrogen phosphate, etc. Although the purity is high and the solubility is good, only these ingredients are considered. To see the effect from the shoots on the shoots, it is not much faster than the general compound fertilizer, and it usually takes 5-7 days to appear on the plants. For vegetable growers, the most intuitive criterion for judging the quality of fertilization is the performance of short-term plants after flushing. In order to achieve rapid effect, plant growth regulators (the main active ingredients in rooting agents), such as nitrophenolate and amine fresh esters, are added to the fully water-soluble fertilizers, so that rooting can be promoted first, and root activity can be improved. The supplemental inorganic nutrients can be quickly expressed on the plants, allowing the farmers to see them.
Plant water growth regulators have been added to the fully water-soluble fertilizers, especially some lower-grade, fully water-soluble fertilizers. The plant growth regulators are also high in content, and they are effective but not lasting after use. In the case of barrel rooting agent, this kind of "only long roots, no fruit" may occur in the case of high nitrogen content of manure in the base fertilizer.
Recommended growers: When choosing a fertilizer for rooting and rooting, please choose a mineral source humic acid fertilizer, seaweed fertilizer, or a combination of mineral humic acid and seaweed.
