Method of fully mechanized rice cropping during two harvesting seasons

Abstract

The invention discloses a method of fully mechanized rice cropping during two harvesting seasons. The method comprises the following steps: A, breed selection: breeds with the growth duration being 120 to 135 days and high tillering capacity are adopted; B, timely seeding: the seeding data is from March 23rd to March 26th; C, reasonable close planting: the mechanical transplanted density is 13 to 18 thousand seedlings / mu; D, fertilization management: nitrogen control and potassium increasing are performed for first rice crop, and bud promoting fertilizer and hole applied fertilizer are respectively applied for ratooning rice within 10 to 15 days after heading of the first rice crop and 3 days after the harvesting of the first rice crop; E, water management: wetness management is performed during the later period of the first rice crop, and alternation of wetting and drying is performed during the middle and later periods of the ratooning rice; F: rice stubble height: the leaf cushion of a top second leaf is kept, namely the stubble height is controlled to be 40 cm; G, bud promoting chemical regulation: bud promoting regulating agent is applied on each of the second day and seventh day after the harvesting of the first rice crop; H, comprehensive control of diseases and pests. The method is simple, convenient to operate, is beneficial to yield increasing, promotes farmers to increase income on the premises that food safety is guaranteed, greatly reduces the labor intensity, improves the labor efficiency, reduces the labor cost, improves the rice quality, and realizes disaster reduction in year of famine.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and more specifically relates to a method for high-yield and high-efficiency cultivation of "one kind of two harvests" rice. Background technique [0002] "One kind of two harvests" of rice refers to the addition of mid-season rice and reserved ratooning rice, that is, on the basis of the high yield of rice in the first season, the regenerative characteristics of rice are used, and certain cultivation and management measures are adopted to use rice piles after the first season of rice is harvested. A season of rice harvested from dormant buds that germinate and grow into spikes. Ragnarok rice has the advantages of short growth period, high daily output, plant saving, labor saving, water saving, labor adjustment, low production cost and high economic benefit. In recent years, the planting area has expanded year by year, and the per unit yield has increased year by year. It is one of the ...
