Technical Overview: When machinery harvests wheat, the entire amount of straw is mechanically chopped and dispersed in the field, and after mechanical rotary tillage is mixed with the soil to return to the field, rice cultivation, seedling throwing, and swinging cultivation are implemented to achieve full wheat straw return. Rice cultivation combined with a lighter rice production technology system. This technology has many functions such as reusing resources, fertilizing farmland, saving labor, and protecting the environment. It is one of the important ways to develop ecological agriculture and promote the sustainable development of agriculture. It can achieve high yield, quality, efficiency, ecology, and safety of rice. The comprehensive goal has significant economic, ecological and social benefits. This technology won the third prize of Jiangsu Provincial Agricultural Technology Promotion Award in 2011.
Increase production and efficiency: 30-40 kilograms per mu, 80-100 yuan per mu.
Technical points:
1. Core Technology 1 Wheat straw mechanically chopped evenly. Harvesting wheat with a Kubota-type combine harvester takes about 10 cm from the field surface. At the same time, the cutting machine is started. The wheat straw is cut to a length of about 10 cm and evenly spread over the field. Or use the Guilin combine harvester to roll the crushed wheat straw and spread it manually.
2 shallow water rotary cultivation technology. After chopped wheat straw was dispersed in the field, the shallow water layer was poured, and after the basic fertilizer was evenly distributed, the wheat straw with shallow water was applied to the field. The water layer is made up of piers at high elevations and water at low levels. This ensures that the muddy grasses are fully mixed and the flatness of the field is improved. After the rotary tillage, the amount of debris is set within 10 roots per square foot.
3 precise water and fertilizer management technology. According to the characteristics of planting methods, the corresponding management of water and fertilizers should be implemented to promote early-onset and strong-breeding of groups, increase the rate of group-forming spikes, promote large-spike, multi-grain, and increase yield. In terms of water management, it is necessary to promptly increase oxygen in the early stage to eliminate poisoning. In the middle period, it is necessary to separate the fields as soon as possible to make the soil heavy and to prevent the root from falling due to soil inaccurately. Fertilizer management, in view of the characteristics of nitrogen uptake in the early stage of paddy fields and nitrogen in the later stage, adjust fertilizer management. In order to control the middle of the japonica rice, the japonica rice should be balanced and fertilized.
2. Complementary technology 1 Adopt light and simple planting methods such as throwing, swinging, and machine insertion. After rotary tillage and leveling, rice can be transplanted by various rice cultivation methods such as throwing, swinging, and machine insertion. Machine transplanting should pay special attention to the transplanting of the soil after transplanting.
2 Cultivate rice robust technology. According to the method of rice cultivation applied after returning to field, we should cultivate suitable casts, pendulums, plugs, or standard seedlings.
3 Integrated pest control technology. According to the forecast and forecast of the local plant protection department, we should do a good job of preventing and controlling diseases, weeds and weeds, transplanting weeds, transplanting weeds, and weeding herbicides for 3-5 days after transplantation to keep the water layer for 5-7 days.
Appropriate area: all rice areas in the province.
The basics of promotion in 2012: The area of ​​promotion and application in the whole province in 2012 was 19 million mu.
Expected target for 2013: The promotion of an area of ​​20 million mu, covering more than 55% of the province's rice area. Mu section of the efficiency of 80 to 100 yuan.
Focus on the promotion of counties (cities, districts): The province's main rice production counties (cities, districts).
Increase production and efficiency: 30-40 kilograms per mu, 80-100 yuan per mu.
