This model produces 900 kilograms of fresh bean pods in the Netherlands, 800 kilograms of fresh corn ear, 4000 to 4,500 kilograms of Chinese cabbage, and a total of 10,000 yuan in output per mu for Sancha, and 7,000 yuan in net income per mu.
First, the selection of varieties of beans in the Netherlands selected pea 4th, food and vegetable pea varieties. Fresh corn is selected from Suyujing No.1, Jiangnan Huadu, Yangtian No.1, and Meiyu No.8. Chinese cabbage was selected for Lukang No. 3, Fengkang 70, Shuishiying No. 11, and Jinshuang 75.
Second, sowing Dutch beans exposed in early November open sowing, before sowing 10 days per acre high-quality farm fertilizer 3000 kg, 30 kg of superphosphate, 10 kg of urea, mixed into the deep plowing 20 to 25 cm after the leveling do. It is cultivated in sorghum, with a width of 110 cm and a width of 20 cm. In the middle of the well-being, open the ditch to broadcast 3 rows of Dutch beans, so that the width of the ditch is 5 cm and the distance between the ditch is 25 cm. In mid-April of next year, a row of fresh corn will be sowed in a row of 15 cm from the trench, that is, two rows of fresh corn will be planted in each row with a plant spacing of 20-22 cm and a density of 4500-5000 plants per mu. Sweet corn must be processed. Space isolation or wrong sowing, different varieties of the same period of sowing need to maintain a distance of 500 meters or more, or use the phased sowing method to stagger the pollination period, the two varieties must be planted more than 20 days difference; the end of July harvest. Timely ploughing after corn sorghum, 3,000 kg of organic manure per acre and 20-25 kg of organic compound fertilizer. After the planting, the soil will be planted. The width of the plant shall be 2 meters wide, and the width of the plant shall be 30 centimeters wide. Row of Chinese cabbage, row spacing 55 cm 40 cm, density 3000 per mu, for moisturizing rain, sprinkle a thin layer of wheat straw after sowing, smash wheat straw on the next day or before emergence, harvested by the end of October.
Third, the field management of Dutch bean field management with the routine. After the emergence of fresh corn and time seedlings, weeding, weeding, 5 to 6 leaves when the Dingmiao, after the Netherlands bean paste to the original planting line of soil all cultivated on the corn planting line and the original trench, the original Dutch bean seeding The line turns into a ditch, which is 25 cm wide and 25 cm deep. For the characteristics of fresh corn stubbornly hiccups in time to promote strong seedlings. When the Chinese cabbage seedling grows to â€œpull the crossâ€, the first time the seedlings are planted. Afterwards, according to the seedling condition, the young seedlings, the seedlings, the seedlings, the seedlings, the timely cultivation and weeding, and the drought-resistant top dressing. In the rosette period, 5 kg of urea per hectare and 500 to 1000 kg of livestock dung are used to chase and fatten the tree-fertilizer. The top 7 to 10 days before filling the heart, then 5 to 10 kg of urea and 500 to 1,000 kg of human and animal manure per acre are promoted. Coiled heart.
4. Disease and Pest Control As fresh corn has a high sugar content, it is vulnerable to damage by corn borers, ground tigers, beetles, etc. It is necessary to use biological pesticides to form granules and put them into the heart. Do not use pesticides in the later period of pollination, and prohibit the use of highly toxic pesticides to ensure the safety of fresh food spikes. The diseases and insect pests of Chinese cabbage mainly include downy mildew, soft rot, aphids, cockroach, cabbage butterfly and diamondback moth. According to the growing trend and weather conditions, 70% mancozeb 600 times solution and 75% chrysanthemum should be selected in time. Clear 600 times liquid to prevent downy mildew, use 25010-6 concentration of agricultural streptomycin to control soft rot disease, use 10% imidacloprid 5000 times or 2.5% kungfufen 5,000 times liquid to control aphids, leafhoppers, cabbage white butterfly, Plutella xylostella.
V. Harvesting, Storage and Transportation: After 15 days of flowering, the pods of N. officinalis are harvested for a suitable period. The suitable harvest period of fresh corn is short. Generally, after 17 to 22 days after pollination, the appearance of yellow leaves is the best time for harvesting.
