Abstract
The invention discloses a water-saving and fertilizer-saving rice planting method. The rice planting method comprises the steps as follows: 1, seed selection: selecting a good-quality and high-yield hybrid rice variety with high fertilizer and water utilization efficiency and good combination property; 2, rice field cultivation: steeping the field timely after harvesting of preceding crops, turning and returning straw to the field, and applying base fertilizer after furrow making; 3, seedling culture and rice seedling transplanting: performing seedling culture and rice seedling transplanting with conventional methods; 4, irrigation; 5, fertilization: after transplanting rice for one week, applying tillering fertilizer, meanwhile, applying booting fertilizer at the booting stage, spraying 0.45%-0.5% of monopotassium phosphate solution on rice foliage during seed setting, and spraying the solution every other one week; 6, harvesting. The field water level at different stages of growth ofrice is strictly controlled, broad irrigation and long-term irrigation are prevented, water can be saved effectively, meanwhile, straw is used for absorbing water and fertilizer automatically, when water layers are dry, water and fertilizer can be released timely, the water and fertilizer requirements of rice can be met, and the method can save about 30% of water and about 20% of fertilizer as compared with traditional planting methods.
Description
technical field [0001] The invention relates to a water-saving and fertilizer-saving rice planting method, which is applied in the technical field of rice planting. Background technique [0002] Rice is one of the most important food crops in my country. my country is a large agricultural country, and rice is grown in many parts of the country. At the same time, my country is also a country with relatively poor fresh water resources. The per capita fresh water resources are only 1 / 4 of the world average. A large amount of water is needed in rice cultivation, so there is a certain conflict between poor water resources and rice cultivation. In the current market, when many people plant rice, they use water and fertilizer at will, which not only wastes a lot of water resources and fertilizer, but also leads to low rice yield, which cannot be planted scientifically. Contents of the invention [0003] In order to solve the above-mentioned problems, the invention discloses a wat...
