Ziyunying Rice Fields No-tillage
Ziyunying can cultivate fertility, improve land cultivation performance, and improve the soil environment. The effect of increasing production is also obvious, which is about 30-40 kg more than that of the non-planted Ziyunying plot. If no-tillage technology is combined with Ziyunying production, labor can be effectively saved, investment can be reduced, costs can be reduced, and production efficiency can be improved. 1. The relationship between Ziyunying production and early no-tillage cultivation Since the beginning of the promotion of no-tillage techniques in rice, the late rice no-tillage technique is easy to operate and has significant effects, while the early rice no-tillage technique is relatively popular due to the impact of field conditions and weather. difficult. The first is that the early cultivated arable land is hard, cracked, and has few weeds in the field before being ploughed by the sun. After destroying the stubborn fields, the water leakage is serious, the water consumption is large, and the soil surface softens slowly and takes a long time. The second is that as early as 3-4 months of rainy weather, the temperature is low, affecting the subtilis fermentation, soil softening schedule and spraying effects. To solve the above problems in rice no-tillage, we must vigorously promote the cultivation of Chinese milk vetch. Because after the destruction of Ziyunying, even if it rains, it rots quickly and the soil surface is softened and has a good quality. This shortens the processing time. After the treatment, the field covers a layer of thick soft humus to reduce the leakage of water, and there is a use of soil. Legislation provides good conditions for no-tillage. Second, Ziyun Ying's production technology 1, soaking germination. Soak in fresh water for 12-24 hours (change the water for 1-2 times during soaking), and pick up and dry. The dried seeds were then piled up to germinate and flipped during the stacking process. See the seed dew shoots, mixed rhizobial bacteria in the room, the seeds and rhizobial bacteria together into the pot, fully mix (rhizobium agent and seed ratio of 1:10), can be sown after drying slightly. 2, choose to sow. To choose the land for irrigation and irrigation is convenient, usually in the middle of October, that is, 15-20 days before the rice harvest is more appropriate, the sowing rate of 1.25-1.5 kg per mu. 3, field management. 1 When sowing, the fields should be kept moist, and avoid waterlogging and bad seeds, but they must also be moistened with water. When winter drought, irrigation "running water" to keep the soil moist, pay attention to drainage after the spring. 2 Minimize mechanical damage while harvesting, and leave 20 cm or more of shading on the top. 3 top dressing. For the first time, the top-dressing plant was wetted with paddy soil 4-5 days before cutting, and 5-7.5 kg of compound fertilizer was applied to the mu; the second time was the use of plant ash before the “winter solstice†and the 8- to 10-millimeter mixture of mixed soil was used. After the rain, it is used as a wintering fertilizer. III. Destruction and no-tillage of Ziyunying In order to apply Ziyunying's production to no-tillage technology, it is possible to directly develop large-scale cultivation of winter species, Ziyunying, for destruction. Also reached the purpose of no-tillage. 1, destroy the dry technical points. 10 days before the start of the rice throwing, no rain was selected, and the water in the fields of Ziyunying was drained (more than 1000 kg per mu of fresh milk vetch). Use a non-productive herbicide (Nongda 400 g/mu or 300 g/mu without trace) and 80 kg of water evenly to spray Ziyun Ying, and keep the field free of stagnant water. Fill it with water after 3 days. 5-7 After the day has reached full rot, you can throw it. Dispose of the front row of dry field water or allow it to dry naturally, apply evenly the following layer of fertilizer: ammonium bicarbonate 15 kg/mu, phosphor powder 20 kg/mu, and flatten the field surface. 2, no-tillage throwing. After 10 days of destroying the milk, Ziyunying can throw a shovel, throw it at the right time and throw it high (about 3 meters away from the field surface). After throwing the field and filling the shallow water layer, it is necessary to constantly check to avoid leaking sun seedlings, which can be achieved within 7 days after throwing. 85% of the standing seedlings, at this time, the first top dressing and weeding, and then the conventional throwing cultivation management can be. IV. Notices Ziyunying stems and leaves must be rotted to dark brown. The water layer must be drained or dried naturally before it will poison the seedlings. If the seedlings are poisoned, immediately return to the water for irrigation and field washing.
