Complete set of rice in wheat fields

The so-called wheat set rice, that is, in the wheat harvest before 16-18 days of the treated rice seedings interplanted in wheat fields, wheat ripening machine when the opening of the chopping device, the wheat straw cut into about 10cm, evenly spread on the field table, any The rice cultivation technology that naturally decomposes into the field is a new type of rice cultivation technology integrated with no-tillage, nesting, dry breeding, exempting insertion, and returning the whole amount of straw. With its provincial, provincial, provincial, and technical training measures in place, it can achieve significant production and income increase. Practice has proved that this technique can save 2-4 labors per mu and increase the income by more than 100 yuan per mu.
First, the characteristics of the seedlings
1, poor early development. Rice seedlings are in shading state, poor ventilation and light transmission, and the plots are relatively arid, so it is inconvenient to apply basal fertilizers. The performances are seedlings, weak seedlings, yellow seedlings, slow leaves, and late tillering. 2, the mid-term outbreak of growth. After the three-leaf stage, there was no contradiction between individuals competing for light in transplanted rice fields in conventional transplanting rice fields. There was no process of planting and transplanting stasis, and 1-8 plants could occur, of which 3-6 were dominant plants. Explosive growth occurred at the end of June and early July, and the number of peak seedlings decreased relatively slowly. 3, ideal for mature phase in the later period. Wheat transplanted rice has no impact on planting injury. The root system is developed and the total amount is large. The above-ground part is in proportion to the underground part. At the same time, the fertilizer effect is exerted in the later stage of straw return. The upper three-leaf leaves are upright, the leaves are dark green, and the flag leaves are both long and wide. Photosynthesis ability. The number of grains per panicle was slightly less, but the seed setting rate and 1000-grain weight were significantly higher than those of conventional rice, and the yield was even or slightly increased with conventional rice.
Second, cultivation points
1, field selection. It is best to use flat fields, three-channel internal and external drainage facilities, convenient irrigation and drainage, and less fields for weeds in wheat fields.
2, pay close attention to legislation. 1 Prepare for broadcast. The amount of seeds used is 6-6.5 kg/mu. Thoroughly remove the grass seeds before soaking, and perform the sun drying earlier. About three days before the sowing of rice seeds, the seeds per acre were soaked for more than 48 hours with an agent such as oxime. 2 do mud coating. Before sowing, mix seed, thick mud, and dry fine soil in a ratio of 1:0.5:2 and knead the seeds into pellets. 3 Determine the reasonable sowing date. The sowing date is generally 10-18 days before harvest, and it is evenly spread according to pods. 4 timely drought seedlings. After sowing, whether it is sunny or rainy days, we must carry out drought-resistant whole seedlings. In case of sunny days with high temperature and insufficient soil moisture, we need to carry out the second drought for 5 days after the first drought. 5 science straw returned to the field. When the wheat ripening machine closes, the cutting device is started and the wheat straw is cut into about 10 cm, and evenly sprinkled on the field table. If there is unevenness, manual dispersion can be used. 6 Keep the humidity in the field. After the machine receives water, the water is poured as soon as possible. After the soil is sucked in enough water, it is put into half ditch water to keep the field moist. 7 do a good job in replenishing and replenishing. This work is done within half a month after wheat is harvested.
3, weed control. 1 Chemical weeding. For the first time, about 15 days after the wheat harvest, the “Benzodichlorodichlorobenzene” powder 75-100g fine powder for water 20kg was sprayed, the field was water-free when sprayed, irrigation was done after 24 hours, and the water layer was kept for about 5 days. Excessive doses of this medicine can cause phytotoxicity. The seedlings are in onion tubes. For alfalfa, calfgrass, broad-leaved weeds can also use "rice 2.5%" 60-80 ml per mu of fine spray of water 20 kg, spray 24 hours after spraying, to maintain the water layer about 5 days. For the paddy field with thousands of gold, “Qian Jin 10%” 60-100 ml can be sprayed on the water, spray water for 24 hours, and maintain the water layer for about 5 days. For example, for the first time in addition to the unfinished rice fields, a second elimination may be carried out about ten days after the application, and the selection of pesticides should be based on the flexibility of the field grass. 2 agricultural control. The water layer was established early in the three-leaf stage of rice and water pressure was used to control the grass. 3 manual removal. Remove the remaining weeds after the removal.
4, fertilizer management. The total amount of nitrogen applied by wheat in rice acres is about 18 kilograms. After the end of the irrigation, the water level is reduced to the level below the surface of the seedlings. 25 kg of compound fertilizer is applied per mu and 10 kg of strong agent is applied. The second fertilizer is applied 10 days after the first fertilization. 30 kilograms or 10-12 kilograms of urea; 10-15 days after the second fertilization, see the seedlings make up the balance of fertilizer, 5-6 kilograms of urea per acre. The remaining leaf age 3.5-4 leaf stage, chase application of flower fertilizer, urea 10-12 kg per mu, 7-10 days after application to see leaf color application of fertilizer, Urea Mushi 5-7 kg, panicle fertilizer can also be used with high Content of compound fertilizer, increase the supply of phosphorus and potassium, promote grouting later.
5, water slurry management. 1 Keep moist before emergence. After harvesting, wheat harvested and nursed the seedlings to ensure that the soil in the field sucked enough water and there was no water in the fields. 2 shallow water ground irrigation during the flood season, avoid deep-seated flooded seedlings. 3 After enough seedlings are exposed in time, in early July, when the number of seedlings reaches approximately 80% of the number of panicles, the dehydration is lightly put on hold. The technique of shelving is used with lightness, grounding, and multiple disposal methods. Before July 25th, it reaches Qingshui rigid board. Tian does not return to the bad standard. 4 Booting, heading stage to maintain the water layer. 5 Intertwined dry and wet during grouting period, water cut off 7 days before maturity, to prevent water cut off prematurely.
