The tomatoes in the greenhouse are seedlings in the shed, and the sheds are separated, and the temperature is easy to control. As long as you choose a good variety and manage it properly, you can achieve high quality, high yield and high profit. Its main cultivation techniques are:
Â
Level the field. When selecting the land, you should pay attention to the rotation of non-solanaceae and cruciferous vegetables for more than 2 years, clean the pastoral, especially to remove the diseased fruit and remove it from the field to burn or bury it deeply. Spray the tree general to disinfect, sterilize and prevent infection. Prevent the spread of strain communities. The shed should be sturdy and durable according to local conditions, and it is strong in wind resistance and heat preservation. The land should be deep-turned, and the bottom fertilizer should be applied to the bottom of the fertilizer, paying attention to the reasonable allocation of various essential elements. The sensation should be appropriate, ventilation and drainage should be convenient, and water should be forbidden.
Â
Seed treatment. After the seeds are selected, they are soaked in warm soup, slowly poured into the pot with 60 °C hot water (three open and one cool), and stirred in one direction while pouring. The amount of water is preferably 2 to 3 times that of submerged seeds . When the water temperature drops to 35 °C, stop stirring, soak for 5 to 6 hours in 35 ~ 25 °C warm water , then remove the seeds, then place them at 25 ~ 30 °C for environmental germination (wash daily with the corresponding temperature of warm water 1 ~ 2 Times), after 2 to 3 days, when half of the seeds are "white", seed dressing with new high-fat membrane can repel subterranean pests and diseases, isolate virus infection, not affect germination and swelling function, strengthen respiratory intensity and increase seed germination rate. .
Â
Sowing at the right time. Seeds that have been germinated are sown on a seedbed that has been prepared in advance. The seedbed soil should be sieved with sterile soil and completely sautéed pigs, dried and milled. After the whole planting, cover the wet soil 0.8 cm, cover the mulch and set up the small arch shed. Spraying new lipid film with 600 to 800 times, soil moisture may be evaporated water, sunscreen drought, frost insulation, anti-soil compaction, and source isolation pest eradication asphyxiation, improve seed germination rate.
Â
Seedling protection. The tomato seedling stage uses a new high-fat film to spray the surface of the plant, which can prevent the infection of the bacteria, improve the ability to resist natural disasters, increase the intensity of photosynthesis, and protect the growth of the seedlings.
Â
Control the shoot to promote flowers. Tomatoes in the greenhouse usually use single-stalk pruning, leaving only one main stalk, and all side branches are completely removed. It is necessary to choose the sunny branch in the morning. In combination with spraying, Huahua No. 3 inhibits the main shoots from madness, forcing the top extract to return to the nutrients. It does not need artificial topping buds instead of hormone killing, transforming growth nutrition into reproductive nutrition, promoting flower bud differentiation, and improving the quality of pollen fertilization.
Â
Rational fertilization. The tomatoes in the greenhouse enter the flowering stage. As the temperature rises, the growth rate of the plants increases and the growth increases. At this time, it is necessary to start to rationally apply nitrogen fertilizer to ensure the nutrient supply of the tomatoes. Applying micro-fertilizer in time, and using root-spray capsule combined with root irrigation, can induce the absorption, digestion and release of nitrogen, phosphorus, potassium and various trace elements in the soil, improve the positive energy of fruit development and optimize fruit quality.
Â
Clever control of blight. After the emergence of bud blight, it is necessary to pay attention to the cultivation of new results of the ear, remove some long branches, and spray a new high-fat film to form a protective film to prevent the invasion of the bacteria; while leaving a good growing inflorescence in the appropriate position, use it Replace lost ears to reduce yield loss.
Â
Preserved flowers and strong fruit. In the greenhouse flowering period, the fruit is fertilized to enhance the pollen fertilization quality, and the cycle fruit set rate is strong, promoting fruit development, no deformity, no empty shell, no glutinous grains, good uniformity, improved quality, and high yield of fruits and vegetables. .
