1. Pharmaceutical soaking method. Seed soaking in warm water for 6 hours, soaking in 200 times potassium permanganate solution for 1 hour, or soaking in 200 times formalin solution for 1 hour, or soaking in 10% trisodium phosphate solution for 20 minutes. After immersion, rinse the seeds with water to kill the virus on the seed surface. 2. Seed treatment method. The seeds to be germinated after bloating are treated at a temperature of about 0°C for 1 day - 2 days, and the seeds to be germinated can also be treated at 1°C - 4°C for 12 hours - 18 hours, followed by transfer To 18 °C -22 °C placed 6 hours - 12 hours, so repeated treatment 7 days - 10 days, can improve the cold resistance of seedlings, speed up the growth and development. 3. Stimulation method. After the seedling grows 1 true leaf, the seedlings are lightly applied to the seedlings 4 times - 5 times a day on the morning and afternoon, and the treatment is continued for 2 weeks. Other management is the same as the routine. This method can prevent seedlings from deteriorating and leggy. 4. Spray the hormone method. When the seedlings grow to 4 leaves - 5 leaves, in order to regulate the relationship between vegetative growth and flower bud differentiation, and coordinate the height and thickness of the seedlings, it is possible to spray 5,000 to 10,000 times the amount of dildoamine or 1,000 times the amount of chlormequat, 10 days - 15 days before spraying again. This method can effectively suppress leggy and form strong seedlings. 5. Root dressing method. Seedling spray 2 times - 3 times 600 times the fertility factor or 9000 times the leaf surface treasure, even after a cloudy day sunny morning spray 0.3% of the sugar or urea liquid can prevent wilting, strong maggots, disease resistance. 6. Spray rare earth method. The spraying of 300ppm--500ppm rare earth solution during the seedling stage and the initial flowering stage can increase the leaf size, darken the leaf color, and the plants grow robustly, increasing the yield by 10%-15%. 7. Plant growth regulators. In order to prevent flowering and fruit drop and increase fruit setting rate, 2.4-D10ppm--20ppm silk flowers or 30ppm--40ppm tomato spirits can be sprayed. However, with the 2.4-D, the labor cost is high, and the pods are prone to appear. In order to prevent the heavy spray from leaking, a “food red†pigment may be added to the liquid for identification. Spraying should be carried out before 10am, and the best period is when the petal is exposed. In order to reduce the workload, each inflorescence can only spray 2 - 6 flowers. 8. Precocious high yield pruning method. The main branch leaves 4 ear fruit to carry out the heart-top capping. When the two lateral branches below the first inflorescence grow to 6 cm or so, they leave one leaf to pick their heart. 2 main crown fruit can also be picked on the main branch topping the heart, leaving 2 - 3 lateral branches under the first inflorescence of the main branch, each side branch rejoining 1 spike - 2 ear fruit picking the top of the heart, each tomato joint 4 ear --6 ear fruit. Both of the above methods can reduce the height of the plant, enhance ventilation and light transmission in the greenhouse, and promote early maturing and high yield of tomato. 9. Pressing stick method. After the fruiting period of the tomato capping period has expired, leave one or two lateral branches proliferated at the bottom of the main stem. When the lateral branches grow to 23 cm - 30 cm, remove the leaves of the collateral branches 2/3, and bend the side branches to the ground, using the earth pressure. Live, the top exposed 2 - 3 leaves, and then watering. Pressure soil can quickly grow a large number of roots. Immediately after the failure of the tomatoes, the main stems of the upper branches were trimmed off and the management was strengthened. The lateral branches quickly blossomed and yielded high yields. 10. Ethephon induction method. When the top of the fruit turns from green to white, use gauze or thread gloves to wipe the fruit gently with 250-500 times the 40% solution of ethephon. Generally, it can be mentioned in the morning for 5 days-7 days. The harvested white-backed fruits can also be removed by dipping in 2000ppm--4000ppm ethylene solution and placed at 20°C-25°C. The color can be colored within 3 days-5 days, generally 5 days ahead of natural maturity- -10 days.
