Embodiment 1

[0015] A method for cultivating moisture in dry land wheat, the wheat field is ridged, and the field ridge width is 40cm, the distance between adjacent field ridges (i.e. the sowing width) is 80cm, and the land (i.e. the sowing width) between the adjacent field ridges is sown, and the sowing row spacing 16cm, and before the soil is frozen in winter and after the wheat stops tillering, the corn stalks (whole plant) are evenly covered on the surface of the field ridge, and the amount of corn stalks is 4500kg / hm 2 .

Embodiment 2

[0017] A method for cultivating moisture in dry land wheat, the wheat field is ridged, and the field ridge width is 60cm, the distance between adjacent field ridges (i.e. the sowing width) is 100cm, the land (i.e. the sowing width) between the adjacent field ridges is sown, and the sowing The row spacing is 20cm, and before the soil freezes in winter and after the wheat stops tillering, the corn stalks are evenly covered on the surface of the field ridge, and the amount of corn stalks is 4500kg / hm 2 .

Embodiment 3

[0019] A method for cultivating moisture in dry land wheat, the wheat field is ridged, and the field ridge width is 40cm, the distance between adjacent field ridges (i.e. the sowing width) is 80cm, the land (i.e. the sowing width) between the adjacent field ridges is sown, and the sowing The row spacing is 16cm, and before the soil freezes in winter and after the wheat stops tillering, the corn stalks are evenly covered on the surface of the field ridge, and the amount of corn stalks is 3000kg / hm 2 .

Abstract

The invention belongs to the technical field of crop cultivation, and particularly relates to a soil-moisture-preservation cultivation method for dry-land wheat. The soil-moisture-preservation cultivation method comprises the steps that ridges are formed on wheat field, wherein the width of each ridge is 40-60 centimeters, and the distance between the adjacent ridges is 80-100 centimeters; seedingis conducted on land between the adjacent ridges, wherein the seeding line spacing is 16-20 centimeters, and the surfaces of the ridges are covered with crop straw. Through scientific and reasonabledesign of the planting line spacing and the ridge width, by covering the ridges with the corn straw, a ventilated and light-permeable environment is formed in a wheat planting area, the wheat population quality is improved, the grain number per ear is increased, the thousand seed weight is improved, the temperature-increasing and moisture-preservation ability of soil is improved, and the yield increasing aim is achieved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a moisture-conserving cultivation method for dryland wheat. Background technique [0002] The development of dryland agriculture in my country has a history of thousands of years. The research on dryland agriculture has been from the division of dryland agricultural types, the water resource status of dryland agriculture, agricultural water collection projects, soil water conservation technology, and the interaction between farmland water and nutrients. The individual researches such as water saving and variety resources have been developed to the application of comprehensive technologies. my country's dry farming technology mainly includes the following aspects: first, the basic research on the development of dry farming, the screening and breeding of drought-tolerant crops and varieties. The second is the use of rainwater. Since rainwater is the only exter...
