Example Embodiment

[0022] Example 1

[0023] A ditching and sowing cultivation method for rice stubble wheat with semi-no-tillage machine includes the following steps:

[0024] 1. Crops layout and selection of wheat varieties

[0025] Early-maturing rice stubble fields, that is, stubble rice fields from the end of September to early October, choose to plant semi-winter wheat such as Yangmai 158 or Zhoumai 22; medium and late sown late japonica rice stubble, from mid-late October to early November Late-sown late japonica rice stubble fields, choose to plant spring wheat; in mid-to-late November, stubble the rice fields, sown early spring wheat.

[0026] 2. Sowing amount and total fertilization

[0027] In the first ten days of October, stubble the paddy field and sown semi-winter wheat fields. The sown amount per mu is 12-13kg, and the total fertilizer input per mu (including pure nutrients) is 45kg: of which 18kg of pure nitrogen, 6kg of phosphorus pentoxide and 21kg of potassium oxide ; From mid-to-lat...

Abstract

The invention discloses a semi-no-tillage machine ditching and broadcast sowing cultivation method of wheat following rice. The semi-no-tillage machine ditching and broadcast sowing cultivation method comprises the following steps: selecting crop rotation and varieties; determining a sowing amount and applying fertilizers; applying base fertilizers and applying 5kg-7kg of urea into rice straw full-amount mulching paddy field base fertilizers to catalyze the rotting of straws; uniformly sowing seeds; managing the wheat following rice and harvesting when the wheat is 100% ripe; drying, storing and selling. According to the semi-no-tillage machine ditching and broadcast sowing cultivation method, the nutrition of soil is increased in the rice straw full-amount mulching paddy field base fertilizers, so that the granule structure of the soil is improved and the nitrogen fixation effect of the soil is increased; before the wheat following rice sprouts after being fertilized and sowed, a rotary cultivator is selected according to farmable soil moisture content and is used for carrying out shallow rotary semi-no-tillage and ditching; ditches are cleaned after the seeds are sowed and seedlings sprout; the water and soil loss is reduced; a cultivation land can be protected, the soil moisture content is improved and the temperature is increased, the direct surface runoff of rainstorm weathers is increased and the water-logging is reduced.

Description

technical field [0001] The invention belongs to the field of crop sowing, in particular to a method for cultivating rice stubble and wheat with a semi-no-tillage machine for ditching and sowing. Background technique [0002] Plant wheat or barley after harvesting rice in rice field. There are rice stubble and wheat in the south and north of China, which are mainly distributed in the Yangtze River Basin. In the north of the Yangtze River Basin, rice and wheat are mainly used for double cropping. In the south of the Yangtze River Basin, except for rice and wheat. And in Shanghai, there are three crops of early rice and late rice wheat (or barley) a year. Since the 1970s, some places in the Huanghuai winter wheat region have promoted the transformation of dry fields into paddy fields and dry rice cultivation, expanding the area of ​​rice planting, thus developing the double cropping system of rice and wheat. The commercial rate of wheat in the area of ​​rice stubble and wheat...
