Embodiment Construction

[0035] The specific implementation mode of the present invention is described in detail below with the 2012 year embodiment in Table 1 as an example

[0036] The embodiment in Table 1 is sowing on October 12, 2011, according to the traditional sowing method, before February 10, 2012, according to the normal management method to ensure the normal growth of wheat. On February 10, 2012, the wheat ear differentiation period began. At this time, the daytime temperature reached 10.5°C, and the nighttime temperature was higher than 2.3°C. Measures were taken to spray potassium chloride in the wheat field, with an amount of 1.5kg / mu; measured on February 18 The ABA content in wheat leaves was 1.42ng / gFW. Since the ABA content was lower than 3ng / gFW, the daytime temperature reached 15.6°C around February 20, and the nighttime temperature was 5.5°C. Topdressing urea was applied at a rate of 15kg / mu. At the end of panicle differentiation, the ABA content in wheat leaves was measured to b...

Abstract

The invention discloses a method for increasing yield by utilizing weather conditions to increase the weight of inferior grains of winter wheat, which includes a fertilization measure for the winter wheat spike differentiation period, a dry-wet alternate irrigation measure for the winter wheat fructification period and an ABA spraying measure for the filling period after the flowering of winter wheat. According to weather conditions, the phasic development process of wheat is artificially controlled, so that the growth and development of inferior grains are controlled, uncontrollable weather resources are actively transformed into useful conditions, and by integrating weather conditions with the usage of exogenous hormone ABA in the phasic development process of wheat, the invention puts forward a complete new set of winter wheat cultivation method which can increase the weight of inferior grains of wheat and the uniformity of wheat grains.

Description

technical field [0001] The present invention relates to a crop cultivation method, especially a winter wheat cultivation method utilizing meteorological conditions Background technique [0002] The yield of wheat is composed of three factors: the number of ears per mu, the weight of grains per ear, and the weight of thousand grains. After several generations of wheat cultivation, the efforts of breeding scientists and the improvement of fertilizer and water conditions, especially the use of chemical fertilizers, the yield of winter wheat has increased from 100 kg per mu in the past. Increase to the current 550 kg per mu. However, with the increase of the number of ears per mu, the cultivation of winter wheat will easily lead to insufficient light in the field, lodging of the wheat, and a decrease in the number of grains per ear and the thousand-grain weight. In view of this problem, the most ideal way to increase yield in wheat production is how to increase the number of gr...
