Row-expanding and plant-strengthening cultivation method for wheat

Abstract

The invention provides a row-expanding and plant-strengthening cultivation method for wheat. The row-expanding and plant-strengthening cultivation method for the wheat is characterized in that after aland is ploughed, ridges and flat furrows are alternated through soil preparation, the ridges comprise high ridges and low ridges, the high ridges and the low ridges are alternately arranged, the height differences among the high ridges, the low ridges and the flat furrows are respectively 25-30 cm and 15-20 cm, two sowing ditches are respectively formed among each high ridge, the corresponding low ridge and the corresponding flat furrow, the wheat is sown according to a row spacing of 29-31 cm, and field management is carried out until the wheat is ripe and harvested. According to the invention, a multi-spike type variety with strong stress resistance and wide adaptability is selected, the row spacing of the wheat is enlarged appropriately, the edge row advantage is fully played, and a wheat population with reasonable structure, strong individuals and strong stress resistance is constructed. Compared with a traditional sowing technology, the row-expanding and plant-strengthening cultivation method for the wheat has the advantages that portions among 1-3 sections of a base is shortened by 3-5 cm, and the stem strength and lodging resistance are obviously enhanced; the ventilationand light transmission conditions of the population are obviously improved, and stem and leaf diseases such as sheath blight, powdery mildew and the like are obviously reduced; and the number of grains per spike is large, the 1000-grain weight is high, and the yield per mu is high.

Description

technical field [0001] The invention relates to the technical field of wheat planting, in particular to a method for cultivating extended and strong wheat plants. Background technique [0002] Wheat is an arbor plant widely planted all over the world. It is one of the earliest cultivated crops in the world. It can be used to make steamed buns, bread, wine, etc., and has a wide range of edible value. However, wheat planting has problems such as many diseases (sheath blight, powdery mildew, etc.) and low yield, and it is prone to lodging when encountering wind and rain during the growth process, resulting in a substantial reduction in production or even extinction. These problems make the current wheat planting unable to satisfy people. life needs. [0003] In particular, the problem of easy lodging is one of the key factors restricting the yield of wheat, and the long internode length at the base is the main factor leading to lodging.

AI Technical Summary

Problems solved by technology

However, wheat planting has problems such as many diseases (sheath blight, powdery mildew, etc.) and low yield, and it is prone to lodging when encountering wind and rain during the growth process, resulting in a substantial reduction in production or even extinction. These problems make the current wheat planting unable to satisfy people. life needs

[0003] In particular, the problem of easy lodging is one of the key factors restricting the yield of wheat, and the long internode length at the base is the main factor leading to lodging. Poor lodging resistance

The root system is underdeveloped and the roots are not deep, which will also cause the wheat plants to fall easily

In addition, wheat sheath blight, powdery mildew, etc. will also cause poor elasticity of the base, damage to the stem tissue, decrease in bending resistance, and cause lodging

[0004] Patent CN103636399B discloses a wheat planting method, which relies on the spraying of control pesticides and corresponding planting management to increase the yield of wheat and improve the ability of wheat to resist drought and lodging, but the average yield per mu is only 450 kg, and the wheat yield is still a lot of room for improvement
