Cultivation method for improving yield of wheat

Abstract

The invention relates to a high-yield culture technique of wheat, including land preparation, seeding, fertilizer application, watering and disease and insect control; the high-yield culture technique is characterized in that: the pattern of double sowing in one ridge with equal row distance and band seeding with broad width is adopted for sowing, and a wheat seeder with broad width is used for sowing. The high-yield culture technique has the advantages that: as the land occupying space of a single plant of wheat is enlarged, the leaves of wheat are not crowed, thus chemical weed killing effect can be greatly improved; the enlargement of the growing area of a single plant is beneficial to a robust individual and good lodging resistant effect; on the basis of fine-seeding, tillering is increased, the development of colony is reasonable, grains are not crowded, the growth state of competing for fertilizer, water and nutrition does not exist among individuals, the wheat has robust growth and strong adverse resistance, the high-yield culture technique is beneficial to large spike cultivars to form more spikes, and multi spike cultivars to form large spikes, thus facilitating larger spikes and more grains and obviously improving yield. The enlargement of the nutrition adsorption area of an individual plant is good for the development of the root system and the enhancement of vitality, and the late green functional period of wheat is prolonged, which can relatively delay the aging time of wheat and is beneficial to increasing wheat grain weight.

Description

(1) Technical field [0001] The invention relates to a grain cultivation method, in particular to a high-yield cultivation method for wheat. (2) Background technology [0002] Since the 1970s, my country's wheat production has been at a low level, and machinery is relatively backward. Large fertilizers, floods, and large sowing volumes often cause late lodging of wheat, which has a greater impact on the increase in wheat yield per unit area. The high-cost, low-yield production mode restricts the development of wheat production, premature root senescence, and malnutrition in the later stage of wheat, making it difficult to achieve high yield. Due to the deep-rooted traditional concept of farmers focusing on varieties, neglecting cultivation, emphasizing fertilizer and water, and ignoring machinery, there are many kinds of wheat planting methods such as small row dense planting, wide and narrow row dense planting, and so on.

High-cost, low-yield production methods restrict the development of wheat production, premature senescence of the root system, and nutritional imbalance in the later stage of wheat, making it difficult to achieve high yields

Due to the deep-rooted traditional concept of farmers focusing on varieties, neglecting cultivation, emphasizing fertilizer and water, and ignoring machinery, there are many kinds of wheat planting methods such as small row dense planting, wide and narrow row dense planting, and so on. Vigorous growth, prominent contradictions between individuals and groups, poor light in the field, small spikes, few grains, and low thousand-grain weight have severely restricted wheat production and the improvement of per unit yield, and restricted the development and improvement of wheat production levels

Fertilizer and water application in traditional wheat field management is unreasonable. Generally, it is applied in early spring, which promotes the growth of ineffective tillers, shades the field, lowers the utilization rate of light energy, and lowers the yield.

[0003] The traditional wheat sowing is small rows or large and small rows densely planted in a line drill (small rows are sown in a narrow width of about 3cm), and the grains grow in a line after they enter the soil and emerge. Crowding, competition for fertilizer, water, and nutrition, resulting in few tillers, poor root system, weak individual growth, poor disease resistance, poor lodging resistance, poor stress resistance, and many ineffective tillers, slow polarization, often resulting in field depression, light The energy utilization rate is low, the ears are insufficient, the ears are small and the grains are small, and the thousand-grain weight is low, which greatly affects the increase of wheat yield
