Rice onion for high yield and efficiency

Through experiments, the rice-onion high-yield and high-efficiency planting model not only changed the traditional rice--wheat-rice-rice-rice planting model, but also ensured the food security, but also improved planting efficiency and achieved a good economy. income. The rice produces 700 kilograms per mu, the output value is 1300 yuan, the organic cultivated value per mu is more than 2,000 yuan; the onion mu produces 5,500 kilograms, the output value is 3,500 yuan, the total output value per mu is 4,800 yuan, and the net income is more than 3,500 yuan.

First, improve cornices and improved varieties. Rice was raised in mid-May, transplanted in mid-June, and harvested in late October; onions were planted in late September, transplanted in mid-November, and harvested in early June. Rice uses high quality and high yielding new japonica rice varieties, such as Zhendao 99 in Jiangsu Province, Lindao 15 in Shandong Province, and Huayan No.6 and Xudao No.3; onion uses yellow varieties of Japanese Sapporo Yellow onion, with an output of 5,500 kg per mu. More than 85% more than the local farmers' varieties.

Second, nurture elites. (1) Paddy rice should be sowed in a suitable period to cultivate the best age. Usually sowed in mid-May, the age of about 30 days is better. Putian must apply basal fertilizer, ripen the soil, cut off milk fats one leaf and one leaf, apply supplemental fertilizer to the three leaves, and strengthen management, control water, skillfully apply fertilizer, and do a good job of pest control work. Bring up the upright, upright, disease-free and suitable age. seedling. (2) The yellow skin onion seedbed is roasted with 200 kg of organic fertilizer per mu, 80 kg of ternary compound fertilizer and flat ridge. The seedbed is soaked with water, and the seed amount is about 1 gram per square meter. Cover fine soil 1-1.2 cm thick after sowing and keep the soil moist for 10 days to keep the seedlings neat and tidy. Pay attention to the removal of weeds at the seedling stage, the main diseases are damping-off diseases, pests have cabbage caterpillars and some underground pests, etc., should be promptly controlled.

Third, accurate quantitative colonization. Rice should be widely planted and sparsely planted, and the planting quality should be improved. Tests have shown that the middle and upper fertility plots are planted with 20,000 holes per acre with a spacing of 13 cm and 25 cm, 3-4 per hole, and about 60,000 basic seedlings per acre. Before the planting of yellow onion, 2500 kg of farmyard manure per mu, 60 kg of ternary compound fertilizer were planted, and the rice seedlings were planted. The use of black mulch film can keep water fertilizer, prevent weeds, and increase the yield by 5%. When transplanting, old seedlings and weak seedlings were eliminated. The spacing was 14 centimeters and 20 centimeters, and about 25,000 acres were planted.

Fourth, accurate quantitative fertilization integrated defense. Generally about 20 kilograms of pure nitrogen per acre, even a moderate increase in thin field. Fertilizer management, to master the principles of promoting, controlling, and stabilizing. Requirements to apply base fertilizer, early application of heavy fertilizer, promote early-onset, early enough seedlings. Pay attention to the prevention and control of rice leaf roller, rice stem borer, rice planthopper, rice blast, and weeds. After the yellow onion is planted, the field management should be watered in time to ease the seedlings. When the spring begins to return to green, it is advisable to lightly pour and apply 20 kg of nitrogen fertilizer per acre. Into the leaf vigorous growth period should be properly strengthened seedlings, inhibiting the growth of leaf. Bulb expansion period requires fertilizer and water, watering should be ground, with water flushing and quick-effective ternary compound fertilizer 2-3 times, each applying 20-30 kg per acre. We often keep the fields moist and drain them after rain. Stop watering 1 week before harvest to facilitate storage.
