Zero-tillage and free-pit- cultivation method for rice stubble-transplanted horsebeans

Abstract

The invention discloses a zero-tillage and free-pit-cultivation method for rice stubble-transplanted horsebeans. The method comprises the following steps: (A) the growing of horsebean seedlings; (B) the making of horsebean border checks: a rice stubble field is set out and ditched to make border checks, the width of each border check surface is 100cm, and the width of each border ditch is 40cm; (C) the row replacement of base fertilizer: the row replacement of the fertilizer is carried out along the inner sides of soil ridges; (D) the transplantation of horsebeans: two rows of horsebeans are transplanted along the inner sides of the soil ridges of each border check, the spacing in the rows is 15cm, the spacing between rows is 60cm, the interval spacing between rows is 80cm, and the field has 6340 plants per mu; (E) the deep ploughing of the border ditches: the border ditches are deeply ploughed 20cm below the surface of the field, and the upturned soil is evenly placed on the surfaces of the border checks; and (F) field management. The cultivation method can be carried out in dry and muddy fields in sunny, cloudy and rainy days, zero-tillage, pit-free stubble transplantation can be carried out, the spacing between rows is enlarged, the spacing in the rows is reduced, close planting and double-row plantation are carried out reasonably, the deep ditches and the heaped soil can prevent flooding and preserve soil moisture, the transplantation of the seedlings can gain the season, and the yield is high and stable because of early plantation on late stubbles.

Description

technical field [0001] The invention relates to a farming method for transplanting winter broad beans in rice stubble. Background technique [0002] Broad bean is a leguminous crop that integrates grain, vegetables, feed, and green manure. Rice stubble is suitable for planting winter broad beans, but in late rice areas, the autumn planting season is tight and the farming period is short. The suitable sowing date is missed, so the sporadic planting area of ​​broad beans is small, the yield is low and unstable, and the benefits are poor. [0003] At present, the no-tillage and hole cultivation method for direct seeding of rice stubble and broad bean specifically includes the following steps: [0004] 1. Make broad bean furrows: Stake out the furrows on the paddy field with rice stubble. The width of the furrow is 100cm, and the width of the furrow is 40cm. One furrow is plowed on both sides. The width of the furrow is 20cm, and the thickness of the furrow is 13cm. [0005] 2...

Problems solved by technology

[0014] The purpose of the present invention is to solve the defects of late sowing of broad beans in late rice areas, and the time-consuming and labor-intensive shortage of drilling holes in the whole plot, change the habit of direct planting of broad beans, adopt seedling cultivation and transplanting, expand row spacing, reduce plant spacing, reasonable dense planting, and deep ditch congestion Soil, planted in wide rows, providing a no-tillage and hole-free method for transplanting rice stubble and broad beans
