Use potato juice to germinate
Cut the potatoes into cubes and freeze in the refrigerator for 3-5 days. Take out the juice after the natural thawing. Soak tomato seeds in potato sauce for 12 hours. Then use a thick, lint-free cloth to cover the potatoes, spread the soaked seeds loosely, cover with polyethylene film to prevent drying, and place in a warm place. After the seeds germinate, they are inserted into the soil for nursery. According to experiments, germination with potato juice can ripen tomatoes 15-20 days earlier than conventional methods.
Scientific colonization of seedlings
The seedlings were planted with sufficient base fertilizer before planting, and then ditching about 7 cm in depth was conducted according to the row spacing, and then the digging points were drilled according to the plant spacing, and the depth was 5 cm. The bottom 1/3 of the tomato seedlings were wiped off. Miaoshungou was placed well. The roots faced the south and entered the ditch toward the north. The cover soil was wiped off until the leaves were removed and the mulch was covered. In the greenhouse cultivation, the lower branches can be cut to promote root growth. According to experiments, the horizontal colonization of tomatoes is generally faster than that of conventional vertical cultivation. The slow seedling period is shortened by 3-5 days, the survival rate is increased by 15%-20%, the harvesting period is 7-10 days earlier, and the yield is increased by 20%-30%.
Foliar farming manure
During the whole growth period of tomato, when the stomata of the tomato leaves are opened at the noon, the fresh cow urine is evenly sprayed on both sides of the leaf, generally increasing the yield by 18%-25%. However, cow urine should not be sprayed about 10 days before fruit picking to prevent fruit surface contamination. In tomato fruit period, about 6% of the concentration of chicken, rabbit manure soak the filtrate directly on the positive and negative sides of the leaf, tomato fruit can be fast, mature, good quality, high yield. After the proportion of the feces liquid is properly prepared, it shall be filled in a wooden barrel or a large tile cylinder and sealed and soaked for 6-7 days. After full fermentation, the mixture shall be uniformly filtered and slag may be used.
Pressure side branching results
After the fruiting period of the tomato, leave 2-3 lateral branches which grow from the bottom of the main stem, make it bent to the ground, press and fix it with the loam, and only 2-3 leaves are exposed at the top and poured once to control the temperature. Humidity (in greenhouses at 20-25°C during the day and 10-15°C in the evening, the air humidity is 45%-55%.) According to the characteristics of the roots of tomato stems, after the decline of the main stem of tomato, immediately The main stem was cut off from the upper part of the pressured lateral branches, and the management of fertilizer and water was strengthened. Generally, the lateral branches could bloom after 15-20 days.
