Embodiment Construction

[0013] The key points of the cultivation technology of the present invention are specifically implemented as follows:

[0014] 1. Adapt measures to local conditions and select fine varieties

[0015] According to regional conditions, it is successful to select medium-japonica, glutinous rice, medium-japonica hybrid rice and indica hybrid rice as ratoon rice with high yield and high quality, cold resistance, disease and pest resistance, strong regeneration ability, wide adaptability, and moderate growth period. The premise is also an important factor for high and stable production. In the past two years, our production practice has proved that all conventional japonica, glutinous rice and medium japonica hybrid rice with a full growth period of 140-145 days can be used as ratoon rice. Low-altitude plain areas can use late-maturing Huayou 63, medium-japonica, and glutinous rice; middle- and low-altitude mountainous areas and semi-mountainous areas are best used as ratoon rice w...

Abstract

The invention provides a culture technology of perennial regenerative rice, which displays advantages by the following: treating in accordance with local conditions and choosing high-quality seed; choosing region and farm land; cultivating, reseeding and fertilizing scientifically timely; managing water scientifically and dormant baked the farm land timely; preventing and wiping out plant diseases and insect pests and birds and rats; harvesting timely and collecting cereal carefully. The invention is characterized by the following: saving labor and cost and early-ripening (using seasons to culture double-cropping paddy); having high and stable yield; being like rice transplanting rice in grain size and bigger than current regenerative with stable culturing; extending high-quality seed to degenerate; adjusting labor stress at busy time and tension in supply of the high-quality seed. The invention improves the yield through using the technology to culture the perennial regenerative rice efficiently, which can achieve about 505. 2kg per mu and the most being 572. 8kg per mu and the yield of two seasons can be more than 900kg or even be a ton of grain per mu If cultures the perennial rice in last season while rice transplanting rice in next season.

Description

technical field [0001] The invention belongs to rice cultivation techniques, and more specifically relates to a perennial root regeneration rice cultivation technique. Background technique [0002] The rice piles (rice roots) of the middle and late rice of the previous year are used to cultivate rice, which is called ratoon rice, or ratoon rice for short. Seeding, raising seedlings, and transplanting rice seedlings, so labor-saving, cost-effective, efficiency-enhancing, production cost reduction (about 30-35%) and other advantages. And because the perennial rice has a significant increase in yield compared with that of the ratooning rice in the current year, and the output of the late-season transplanted rice can be late and super early, or it can take advantage of the high-yield and abundant harvest of the double-cropping ratooning rice. However, the main disadvantages of existing ratooning rice are low yield and small grains. Contents of the invention [0003] The purp...
