Colonization to fruit set
The management of the Japanese standard: It is necessary to make the plants grow vigorously, but also to prevent the plants from being leggy, and to ensure that the buds are budded and the fruit set is good.
(I) Cultivation Management
1. Before the planting, the greenhouse must be kept under high temperature for disinfection purposes. The agricultural operation process is watering - sheds - deep plowing - leveling the land - spreading manure - shallow digging. Each greenhouse should be fully cooked 6-8 cubic meters of organic fertilizer. Organic manure must be decomposed and fermented before it can be applied. During the decomposed process, 50 kg of diammonium phosphate, 80 kg of superphosphate and 40 kg of potassium sulfate can be added. In the old shed area, 150-200 kilograms of soil conditioner was used for the race, and it was applied to the ground 15 days before the transplant. Root nematodes must be controlled before colonization. Usually 15 to 20 centimeters deep trenches are opened at a distance of 24-33 centimeters before the planting, and the line g (Weibaimu) and Jiamei Jinli diluted liquid are poured into the ditch, and the cover soil is then practical. Thirteen days later, ridges were ploughed and planted after being distributed.
2, ridging planting and peace can be planting planting, flat planting after planting in the cultivator into a ridge. When planting, it is necessary to bring a complete soil, and pay attention to sparse planting. General requirements for the spacing of 90 cm, spacing 40-45 cm, or the size of row cultivation, 110 cm large rows, 70 cm small rows, the density of 2200 per acre. Colonization was performed according to the planned spacing of rows of trees. Each hole was filled with 100-150 g of rotted cakes. After mixing with the soil, the seedlings were placed in the holes so that the seedlings were flush with the ridge surface. Water was poured in the holes and the soil was covered with water.
3, planting when planting water, slow seedlings after pouring water, continuous three times of cultivator, cultivating deep plough cultivating through the last time when the cultivator with the cultivator in the planting near the application of organic fine fertilizer, and then soil into a ridge, tightly cover the mulch. After catching the seedlings, the top coat was applied 15-20 cm away from the plants. The second time of topdressing was sitting on the fruit of the first inflorescence, and the fruit was like a walnut, and it was flushed with water.
4, temperature and humidity management
Since the tomato seedlings will have a rapid growth period after being planted, the temperature and humidity requirements for the greenhouses are relatively high. Therefore, during the summer and autumn seasons, the membranes on the sides and both ends of the greenhouse should be opened so that the daytime temperature in the greenhouse does not exceed 32°C. In the winter and spring season, only the two ends of the greenhouse cannot be opened and the daytime temperature in the greenhouse is maintained. At about 28°C, the night temperature should be 15-18°C and the humidity should be controlled within 40%.
5, when the weather is clear and sunny, do not expose the grasshoppers in the morning to prevent the seedlings from falling down. If the phenomenon of inverted seedlings occurs, promptly cover the grass cover and gradually uncover it.
(B) Pest Control
The high temperature in the early stage is prone to various diseases such as root rot (dead plant), early blight, and leaf mold, etc. Sclerotinia may occur in individual greenhouses. In November, prevention and control of gray molds were focused.
1, vents should be sealed with flood control nets to prevent the invasion of insects.
2. Watering the membrane or watering with drip irrigation.
3, about 5 days after colonization, spraying 600 times liquid with Diconazole again to prevent drought, spot blight and leaf mold.
4. Spray Jin Lei Duo Mi 600 times every 15 days to add virus killing agents to prevent root rot and virus diseases, and prevent and control early blight. Spraying focuses on the southern part of the greenhouse.
5, the prevention and control of leaf mold with high-efficiency bactericide 1500 times the world's high liquid spray even 2-3 times at the same time for early blight and anthrax disease also has a very good control effect.
6, if there is whitefly spray Aketai 5000 times and kung fu 2000 times.
7, promptly remove the remaining petals on young fruit to prevent botrytis.
