Lodging-free cultivation method of super high-yield rice

Abstract

The invention discloses a lodging-free cultivation method of super high-yield rice. The lodging-free cultivation method of super high-yield rice comprises the following steps: (1) carrying out soil preparation, namely digging a plurality of gullies in the conventional paddy field, wherein the gullies are 20-35cm in depth and 30-55cm in width, a root-inducing and seedling-growing fertilizer is continuously stirred into the dug soil to form fertilizer soil during gulley digging, the fertilizer soil is laterally deposited between ditches to form long ridges at intervals, and the long ridges are 15-30m in width; (2) planting, namely planting rice seedlings on the long ridges by properly adjusting according to different variety densities; (3) irrigating, namely irrigating water into the gullies after transplanting rice seedlings, protecting the seedlings in deep water for 2-3 days after rice seedlings are transplanted, wherein the water in the gullies is 22-37cm deepth, the water in the gullies is 18-32cm in depth in a returning green stage and a tillering stage; drying the paddy field for 7-10 days at the beginning of July, carrying out intermittent irrigation by using phreatic water in the middle stage, the water in the gullies is 16-29 cm in depth in heading stage, intermittently drying and wetting after full heading, and draining water after yellow ripening stage; (4) harvesting, namely harvesting and threshing after ripening, and finally storing the rice in a warehouse. The lodging-free cultivation method of the super high-yield rice has the characteristics of high yield increase, no lodging and high quality of rice.

Description

technical field [0001] The invention belongs to the field of agricultural planting, in particular to a method for cultivating ultra-high-yield rice without lodging. Background technique [0002] my country is a populous country, which feeds 21% of the world's population with 7% of the world's arable land. At present, the contribution rate of agricultural science and technology to China's agricultural production increase is about 35%, and the contribution rate of agricultural developed countries in the world is more than 60%. The Chinese government has determined and is working hard to implement the strategy of developing agriculture through science and education, and strives to gradually narrow the gap between China and the developed countries in the field of agricultural science and technology. By 2000, the contribution rate of scientific and technological progress to agriculture will increase to 50%, and by 2030 it will be close to that of the world's developed countries. ...
