Method for improving wheat yield per unit area in Huang-Huai region

Abstract

The invention discloses a method for improving the wheat yield per unit area in the Huang-Huai region. The wheat yield per unit area is improved by developing and using large-grain hybrid wheats.

Description

[0001] 1. Technical field [0002] The invention belongs to the field of crop breeding and cultivation in the field of agricultural science and technology. [0003] 2. Background technology [0004] Wheat has strong adaptability, wide distribution, and many uses. It occupies an important position in the grain of the world and my country, and is particularly important in the Huanghuai region of my country. Planting wheat can use light and temperature resources in autumn and winter, which is conducive to improving the multiple cropping index and improving land utilization. . [0005] Predecessors have done a lot of research work on increasing the yield of wheat per unit area. The plots with higher yield per unit area in various places have relatively similar yield levels, suggesting that it is more difficult to increase it significantly. [0006] 3. Contents of the invention [0007] Under the background of the upper limit of the number of spikes per unit area, replace the large...
