Method for intercropping winter rapes and potatoes on middle-season rice crop

Abstract

The invention discloses a method for intercropping winter rapes and potatoes on middle-season rice crop. The method for intercropping the winter rapes and the potatoes on the middle-season rice crop comprises the steps of (A) preparing rest-balks, wherein the width of the faces of the rest-balks is 120cm, and the width of the furrows of the rest-balks is 40cm; (B) applying base fertilizer, wherein the base fertilizer for the rapes and the base fertilizer for the potatoes are simultaneously scattered and applied to the floor field of the faces of the rest-balks; (C) sowing seeds, the rapes are sowed in line on the upturned soil close to the edges of the rest-balks, the sowing width is within 10cm, ten thousands rapes per mu are reserved, the potatoes are arranged and sowed in the rest-balks, the planting distance is 22cm, and 1894 holes of the potatoes are planted per mu; (D) carrying out straw covering, wherein the seed potatoes are covered by straw for 6-7cm, and the parts of the sowing width of the rapes are not covered by the straw; (E) carrying out deep furrow hoeing, wherein the furrows of the rest-balks are hoed deep to 25cm under the field surface, and soil blocks are evenly moved and placed to the parts without the rapes or the potatoes; (F) carrying out soil covering, wherein if the weather is sunny after the seed sowing of the rapes, around 2cm crumbing soil covers the ports of the sowing width; (G) carrying out hilling, wherein after the seedlings of the potatoes are all emerged, the furrows of the rest-balks are cleaned, and the soil is beaten to carry out the hilling; (H) harvesting the potatoes, wherein the straw in the rest-balks is pushed aside, and the potatoes are harvested; (I) carrying out management, wherein the technologies of good seed application and promotion, potato accelerating germination sowing and the like are applied and popularized, and daily field management needs to be carried out well.

Description

technical field [0001] The invention relates to a cultivation method for potatoes, in particular to a cultivation method for intercropping autumn potatoes with middle rice stubble and winter rapeseed in the south. Background technique [0002] The Yangtze River Basin in southern my country is the main production area of ​​winter rapeseed. After the mid-season rice is harvested around September 10, it is the stubble for planting rapeseed, and it is also the period for planting autumn potatoes. Reasonable farming methods, intercropping autumn potatoes with winter rapeseed, do not occupy the autumn planting area, develop autumn potato production, increase grain output, and increase farmers' income. [0003] At present, no-tillage and hole planting methods are adopted for medium rice stubble rapeseed, and the specific method includes the following steps. [0004] 1. To make a furrow, the rice stubble field is made into a furrow, the width of the furrow is 120cm, the width of th...

Problems solved by technology

[0014] The purpose of the present invention is to overcome the defects of the existing medium rice stubble rapeseed square holes that are labor-intensive and time-consuming, cannot be intercropped, and rice straw cannot be returned to the field, and provide a cultivation method for middle rice stubble winter rapeseed intercropping autumn potatoes. Drill sowing, expand the row spacing and reduce the plant spacing, grow potatoes in the middle of the rapeseed bed, cover the seed potatoes with straw, and deep ditch to choke the bed
