Planting method for high-yielding rice

Abstract

The present invention discloses a planting method for high-yielding rice, and the planting method includes the following steps: A, planting broad beans in rice fields, harvesting the broad beans, conducting green manuring and water retting on the harvested broad beans, and applying base fertilizers to the rice fields; and conducting water control on rice seedlings with a seedling age of 15-20 days and a seedling acclimatization for 2-3 days; B, conducting rotary tillage, ridge separating and irrigation on the rice fields, and transplanting the rice seedlings; C, topdressing the rice seedlings with compound fertilizers to promote rice tillering after roots and stems of the rice seedlings are living; D, maintaining a water level of the rice fields at 3-5 cm during the rice tillering stage, topdressing the rice seedlings with urea, potassium chloride and calcium superphosphate, topdressing the rice with N-P-K compound fertilizers with an amount of 80-110 kg / mu and spraying biological pesticides when the rice is in the heading stage; topdressing the rice with the compound fertilizers mentioned in step C with an amount of 25-40 kg / mu when the rice is in the irrigation stage; and cutting off the water supply and drying the rice fields 7-10 days before rice maturity, and harvesting the mature rice. The planting method makes the rice high in yield, good in quality, and less in pesticide residues.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for planting high-yield rice. Background technique [0002] Rice is the main food crop in our country, and it is widely planted in South China, Central China, North China, Southwest China, Northeast China and other places. The rice planting industry supports our agricultural planting industry and provides rice grain to the people of the whole country and even the people of the world. The existing rice Planting methods often have the defect that yield and quality cannot be taken into account, and cannot meet the needs of growing agriculture. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a high-yield rice planting method, which has high yield, good quality rice and less pesticide residues. [0004] A kind of planting method of high-yield rice that the present invention proposes, comp...
