Cultivation mode of spring wheat seed storing in field in winter

Abstract

The invention discloses a cultivation mode of spring wheat seed storing in the field in winter. Systematic study is performed on the sowing date, sowing amount, sowing depth, soil temperature, soil moisture and other yield limiting factors of wheat whose seeds are stored in the field in winter in a traditional spring wheat planting area. The cultivation mode of spring wheat seed storing in the field in winter includes the four steps: (1) tillage and soil preparation and autumn irrigation and moisture storage, (2) sowing date adjustment, (3) high-quality sowing, and (4) management after sowingis conducted. Seed storing in the field refers to a cultivation mode that traditional wheat sowing in spring is changed into sowing in late autumn and early winter, the seeds do not germinate in winter, and seedlings emerge in the next spring, and the mode is called seed covering in soil or spring wheat sowing in winter during production; and the mode can be applied to both spring wheat variety planting but also winter wheat variety planting. Through the cultivation mode, the problems of serious waste of light and temperature resources after spring-sowed wheat is harvested in the north, a lowmultiple cropping index and difficult increase of the total grain output in the whole year are solved.

Description

technical field [0001] The invention relates to a cultivation mode of crops, in particular to a cultivation mode of "field seeding" of spring wheat in winter. Background technique [0002] Inner Mongolia Autonomous Region is my country's largest "one-cropping a year" main spring wheat producing area. The sown area and total output of wheat account for more than 1 / 3 of the country's spring wheat. The production of spring wheat in Inner Mongolia is restricted by factors such as long emergence period, short tillering period, short panicle differentiation time, short grain filling time, dry and hot wind in the later period, and high temperature forcing ripening. At the same time, the frost-free period of more than 50 days after the harvest of spring wheat in this area cannot be used, and the light and temperature resources are greatly wasted. Relatively speaking, planting winter wheat has a longer growth period and can accumulate more photosynthetic products than spring wheat. ...
