Embodiment Construction

[0032] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0033] The key of the technical method of natural additive breeding of winter wheat in dry plains of the present invention has eight mutually coherent steps, which must be interlocking and tightly connected. The wheat seeds involved in the present invention are collected in Shaanxi Province, China.

[0034] 1. Add time.

[0035] Wheat addition is to achieve the goal of wheat seed propagation twice a year. The start time should be early to save time for later wheat growth and development. Generally, it is carried out 20 days after wheat flowering. The young seeds collected at this time have germination ability, and the later The better, but it should not exceed 30 days, and it is better to carry out in mid-June in Changwu area.

[0036] 2. Substitute materials.

[0037] The propagating material selected for the additional breeding of wheat is wh...

Abstract

The invention discloses a method for natural generation-adding breeding of ariplain winter wheat. The method comprises the steps of generation-adding time; generation-adding material; low temperature sprouting; vernalization; timely transplantation; shading treatment; later period film covering and warming; and harvesting and sprouting seeding. According to the method, the cost is reduced, the energy consumption is low, a technology is simple and easy to operate, and the method is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and relates to a method for natural multigenerational breeding of dryland winter wheat. Background technique [0002] Winter wheat is planted in the Weibei plateau at an altitude of more than 1,000 meters. The growth period is as long as 270 days, and the wintering period is close to 120 days. The normal growth and development time of wheat is less than 150 days. The wheat can only be grown once a year. It is time-consuming, slow and inefficient to carry out wheat variety selection and wheat breeding in this area. Contents of the invention [0003] In order to solve the technical problems existing in the prior art, the present invention provides a method for natural multigenerational breeding of dryland winter wheat, which improves the efficiency of wheat breeding and breeding of improved varieties, accelerates the pace of wheat variety improvement, shortens the time limit for wheat varie...
