Embodiment 1

[0023] A high-yield and high-efficiency double-cropping rice field planting pattern, comprising the following steps:

[0024] a: Garlic is planted in winter, after the harvest of late rice every year, ditches, furrows, rakes, fertilization, sowing, and 51% three-element compound fertilizer 750kg / hm 2 , rapeseed cake 750kg / hm 2 As base fertilizer, apply urea 150kg / hm 2 As topdressing, the sowing rate of garlic is 2475kg / hm 2 , the row spacing of garlic plants is 15cm×6cm, harvested 15 days before early rice transplanting in the second year;

[0025] b: plant early rice, sow on March 25 every year, transplant on May 1, the seeding rate of early rice is 300kg / hm 2 , the transplanting row spacing of early rice is 23cm, and the row spacing is 19cm. Early rice is fertilized with basal manure, tiller manure and ear manure for 3 times. The basal manure is once applied before rice transplanting. 2 o 5 12%) 420kg / hm 2 , Urea (N46%) 165kg / hm 2 and potassium chloride (K 2 O60%) 10...

Abstract

The invention relates to the technical field of crop planting and discloses a high-yield and high-efficiency double-cropping rice field planting mode. The high-yield and high-efficiency double-cropping rice field planting mode includes the steps of a, garlic planting in winter, namely performing ditching, bedding, raking, fertilizing and sowing after late rice is harvested every year and carryingout harvest at least 12 days before transplanting early rice in the second year; b, early rice planting, namely performing sowing from March 20 to March 30 every year, transplanting from April 25 to May 5 and harvesting from July 15 to July 25; c, late rice planting, namely performing sowing from June 10 to June 20, transplanting from July 20 to July 30 and harvesting from October 15 to October 25. Planting the garlic during winter leisure in double-cropping rice field can effectively make use of photothermal water resources in the winter of the double-cropping rice field, ensure that the soilis good in condition and avoid reduction of soil fertility and the like caused by the idle in winter to affect planting of subsequent double-season rice, both the economic income of the winter and the yield of the double-cropping rice are increased, and the economic benefit is improved again.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a high-yield and high-efficiency double-cropping paddy field planting mode. Background technique [0002] The middle and lower reaches of the Yangtze River are the main production areas of double-cropping rice in my country. Idle farmland in winter and low economic benefits have become the key factors restricting the sustainable development of rice fields in this area, seriously affecting the enthusiasm of farmers to grow rice. The main traditional planting of double-cropping rice fields in this area The modes are "winter slack-double-cropping rice" and "milk vetch-double-cropping rice". Among them, the "winter slack-double-cropping rice" model failed to make full use of the light and hot water resources of the double-cropping paddy field in winter, resulting in waste of resources and affecting the physical and chemical properties of the paddy field soil, resulting in low...
