Problems solved by technology

However, the Eastern Hebei region has not achieved two crops per year in a natural year (January-December)
[0004] In eastern Hebei, affected by factors such as latitude and climate, the annual frost-free period is about 190 days, and the accumulated temperature above 0°C is about 4200°C. Traditionally, grain crops can only be grown once a year. If only one season of grain crops is grown in a year It will waste light and heat resources. If you want to grow two seasons of food crops (such as winter wheat + summer corn), you will face the problem of insufficient light and heat resources, that is, there will be a situation of "more than one season and less than two seasons".
Therefore, in the eastern Hebei region, it is impossible to achieve two crops per year, resulting in low grain yield per mu, inability to maximize resource utilization, and low economic benefits.

Embodiment 1

[0033] A kind of cultivation method of spring wheat and summer valley double cropping comprises spring wheat cultivation and summer valley cultivation, wherein the steps of spring wheat cultivation are as follows:

[0034] (1) Soil preparation: In early spring or before winter, the land should be prepared to be level, free of soil clods and pits, with good moisture content, top pine and bottom solid. When preparing the land, apply 20kg of compound fertilizer such as diammonium phosphate as the base fertilizer per mu. After applying the base fertilizer, proceed Plowing;

[0035] (2) Spring wheat sowing: select the spring wheat seeds of the "Jinqiang No. 10" variety, sow the seeds in the first ten days of March, soak the seeds with 1% quicklime solution for 12 hours five days before sowing, wash them with clean water and put them in the sun to dry 3 days, when sowing, the sowing depth is about 3cm, the seeding rate is 18kg per mu, and the basic seedlings per mu are about 400,000...

Embodiment 2

[0050] A kind of cultivation method of spring wheat and summer valley double cropping comprises spring wheat cultivation and summer valley cultivation, wherein the steps of spring wheat cultivation are as follows:

[0051] (1) Soil preparation: carry out land preparation in early spring or before winter. When preparing the land, it should be flat without soil clods and pits, with good moisture content and firmness on the top and bottom. When preparing the land, apply 20kg of compound fertilizer such as diammonium phosphate and 1500kg of organic fertilizer per mu as base fertilizer;

[0052](2) Sowing: Select the spring wheat seeds of the "Jinqiang No. 10" variety to be sown at the top of March, soak the seeds with 0.1% potassium dihydrogen phosphate solution for 12 hours 4 days before sowing, wash them with clean water and put them in the sun Sun for 2 days, the sowing depth is about 4cm when sowing, the seeding rate is 20kg per mu, and the basic seedlings per mu are about 420,...

Abstract

The invention discloses a double-cropping cultivation method of spring wheat and summer millet in a natural year. The method comprises spring wheat cultivation and summer millet cultivation. The spring wheat cultivation method includes the steps of land preparing, seeding, irrigating and fertilization, prevention and treatment of disease and pest damage, harvesting and the like. The summer milletcultivation method includes the steps of land preparing, fertilization, seeding, thinning, weeding, harvesting and straw returning. A double-cropping mode in one natural year, namely, a spring wheat and summer millet one-year double-cropping cultivation technique, can be achieved in an eastern Hebei region (or regions with similar natural ecoclimate) under natural ecological conditions, the cultivation technical mode herein makes full use of light and heat resources, the problem of insufficient utilization of light and heat resources or insufficiency of light and heat resources of the easternHebei region is solved, and grain yield per unit land area is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a double-cropping cultivation method for spring wheat and summer valley. Background technique [0002] Eastern Hebei generally refers to the eastern part of Hebei Province and some of the surrounding counties of Beijing and Tianjin. This region is geographically close, has the same regional natural ecological climate characteristics, similar agricultural industries, and similar agricultural production methods. place. [0003] The food planting in the eastern Hebei region is mainly spring corn planting, which is cooked once a year; winter wheat is planted in October of the previous year, and summer corn is planted after winter wheat is harvested in late June of the following year (due to the limitation of light and heat resources, it is difficult for summer corn to grow normally. mature, generally planting fresh corn or silage corn) cultivation mode; there is also...
