Efficient cultivation of zucchini and cauliflower in greenhouse

Zucchini seedlings were raised with Zaoqing first generation variety. Raise seedlings in a nutrition bowl in the greenhouse, using 300 grams of seeds per mu. Soak seeds and accelerate germination to dew and sow seeds, 1 seed per bowl, cover 1.5 cm thick loose nutrient soil, cover with plastic film. Raise the temperature as much as possible before emergence and keep it at 30: 33 ℃ during the day. After finishing the seedling, the temperature should be cooled properly, 2528 ℃ in the daytime and more than 8 ℃ at night. Pay attention to ventilation in the daytime and cover the grass grass at night. The age of colonized seedlings was about 40 days. 5000 kg of mixed fertilizer and 50 kg of compound fertilizer are applied per mu. The border surface is 100cm wide and the border ditch is 30cm wide. Two rows were planted on each border, and the plant spacing was 50 cm. After planting, a small arch shed was built to cover the grass. Close the greenhouse in front of the living plant, and remove the grass from the small arch shed during the day, so as to increase the temperature and slow down the seedlings. After slowing down the seedlings, the small arch shed film and grass clover were removed during the day and kept at 25: 28 ℃ in the daytime and 10: 15 ℃ at night. It is difficult to pollinate naturally in greenhouse cultivation, so artificial pollination is needed. After the melon sat down, the expanded melon fertilizer was applied once, and the compound fertilizer was applied 30 kg per mu. Root melons should be picked in time, and fertilizer and water should be applied every time they are picked. Disease and pest control aphids with imidacloprid, leaf miner with avermectin and cypermethrin, cabbage insect with cabbage, Yitaibao, leaf diseases with disinfectant alum and chlorothalonil. Japanese Snow Mountain varieties were selected for cauliflower breeding. Using sunshade net to cover seedlings, 25 grams of seeds per mu of field and 30 square meters of seedbed. Select a high-lying field, apply 200 kg of rotten soil fertilizer, 200 grams of mancozeb and 50 grams of phoxim in every 30 square meter seedbed, turn deeply, flatten and fine, make an underground border 120 cm wide, irrigate the bottom water, infiltrate and sow, cover 0.5 cm thick soil, cover the mulch, and finally insert the arch frame to cover the sunshade net. Uncover the plastic film after emergence, cover the sunny day from 10:00 to 4 pm, the rest of the time, not cover in cloudy days, cover with film to prevent Rain Water erosion in rainy days. The age of the seedlings was about 35 days. Apply more than 3000 kg of soil miscellaneous fertilizer, 50 kg of ammonium bicarbonate and 30 kg of compound fertilizer per mu, turn deeply and make a high border 80 cm wide, with 2 rows per row, with a spacing of 40 cm, and irrigate enough water when planting. During the whole growing period, the soil was wet and dry. After slowing down the seedlings, the fertilizer was applied once, and the urea was 10-15 kg per mu. During the flowering and heading period, combined with watering, the three-yuan compound fertilizer of 25kg / mu was used as flower ball fertilizer. Pest control is more serious in summer, such as Pieris rapae and Plutella xylostella, which can be controlled by cabbage, Yitaibao and so on. The main diseases are black spot, root rot and so on, which can be controlled by chlorothalonil and carbendazim.
