With the deepening of the adjustment of agricultural structure, in the past two years, the author conducted a wheat non-pollution cultivation experiment of carrots, the average yield per acre of 4100kg, carrots with a single root weight of about 200g accounted for 82.5% of the total output, basically reached the export standard (no blue The head, three red meat, five roots, smooth surface). Compared with traditional wheat crops, intercropping maize has increased 200-300 yuan per mu.
1 Selection of improved species
Should choose disease-resistant, high-quality and high-yield, strong resistance, good varieties of goods. Japanese Kuroda five inch can be preferred. Its characteristics are that the leaves clusters are upright, the bottom of the root is blunt, conical, 18~25cm long, the meat is orange-red, the head diameter is about 4cm, and the single root mass is about 180g.
2 Debris, soil preparation and ridging
After the end of the wheat harvest, we must promptly exterminate and deep plowing, combined with deep plowing 5000 kg of organic fertilizer per acre, 50 kg of NPK fertilizer, and the organic fertilizer must be fully decomposed and finely crushed for full-scale application. Unripe or uneven fertilization, will damage the main root and cause fork roots, leveling and fine ridged, ridge distance 60cm, ridge height 20cm, ridge type 2 rows, spacing 20cm, spacing 11-13cm, planting 30,000 per acre Around the line, ridges can be applied with 10 kg/mu urea to promote seedling growth.
3 timely sowing
Adequate watering before sowing to keep the soil moist. Generally, the soil moisture is maintained at 65% to 80%. Seeds are planted around July 10, harvested in late October or early November. In the ridge, the row spacing is 20cm and the ditch is dry and sowing. The depth is about 1.5cm, and the cover soil is flat. The average amount per mu is 0.8-1.0kg. The herbicide was sprayed after sowing, with 33% weeding and 150g per acre, and 45kg water, even spraying.
4 Field Management
Wheat bran carrots are in high temperature season and the climate is dry. Before the emergence, the rice can be filled with large furrows to keep the soil moist. After the emergence of the rainy season, the seedling root system has poor resistance to waterlogging, and it is necessary to pay attention to rowing. Usually, we must master the principle of seeing wet, small water pouring. During seedlings, 2 to 3 thinning and tillage weeding should be carried out. When the seedlings have 2 to 3 true leaves, the first thinning is carried out to maintain the spacing of the plants from 3 to 5 cm, and combined with shallow tillage and weeding soil. When the seedlings are 3 to 4 true leaves (about 10cm in height), the second time the seedlings are planted, the seedling distance is about 6cm, and when 5 to 6 leaves are true, the seedlings are dislocated and the plant spacing is kept from 11 to 13cm. At the same time, the weeding and weeding are performed once. For the first time, the top-dressing nitrogen-phosphorus-potassium compound fertilizer (15kg) was applied. Into the leaf growing season, we must properly control the water, to carry out cultivator seedlings to prevent leaf clusters and affect the growth of fleshy roots. When the root of the fleshy root enters the period of enlargement, there must be sufficient water and fertilizer supply. For the second topdressing combined with watering, 30 kg of N, P and K compound fertilizers dominated by P and K fertilizers may be applied. When fertilizing, it may be applied between small rows, or it may be applied in the middle and lower part of the ridge shoulders, then the soil is covered and the soil is cultivated in time. Avoid the formation of a green head on the ground with fleshy roots, and no quick-acting nitrogen fertilizer should be used within 20 days before harvesting.
5 Pest control
Wheat bran carrot is in high temperature and rainy season, prone to mildew and soft rot disease. It can spray 65% ​​mancozeb 600 to 800 times in the early stage of disease. Agricultural streptomycin 100mg/kg spray. For pests, 20% cypermethrin 2000 times solution or 2.5% emulsifiable EC can be used for spraying and spray control. 15 days before harvest, drug use was stopped and timely harvested.
