Embodiment Construction

[0050] The technical solution of the present invention will be further described below in conjunction with specific embodiments.

[0051] A method for adding three generations of sorghum breeding materials a year, comprising the following steps:

[0052] Step 1: Early breeding and management technology of the first season materials (first generation materials)

[0053] In February, seedlings were raised in houses with good lighting conditions and heating conditions (indoor heating from February to March in Xinjiang);

[0054] 1) Prepare the nutrient soil in mid-February;

[0055]The main material is made of 7 parts of loose and fertile field topsoil that has not been planted with sorghum crops, plus 3 parts of decomposed organic fertilizer, mixed and sieved, and auxiliary materials: 0.5 to 1 kg of diammonium phosphate per cubic meter of nutrient soil , NPK compound fertilizer 0.5-1 kg; in addition, add 80-100 grams of 50% thiophanate-methyl or 50% carbendazim powder per cubi...

Abstract

The invention discloses a sorghum breeding material generation adding method for obtaining three generations in one year. The sorghum breeding material generation adding method comprises the following steps that (1) early seedling breeding and management are carried out on first-cropping materials, (2) transplantation conditions of first-generation sorghum materials are determined, (3) temperature and humidity adjustment and management after transplantation are carried out on the sorghum materials in a greenhouse, (4) the harvest time of the first-generation materials is determined, (5) seed treatment is carried out before the first-generation sorghum materials are sown, (6) the germination rate of seeds produced by the second-cropping sorghum is controlled, and (7) third-generation seeds are managed when bred in the south. According to the sorghum breeding material generation adding method, one generation is added locally by means of the green house, another generation is added by means of special climate conditions in Hainan province, as a result, the generation adding technology for obtaining three generations in one year is realized, by the adoption of the generation adding technology, the sorghum breeding time in Sinkiang can be shortened, and the breeding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and specifically relates to a method for adding three generations of sorghum breeding materials a year. Background technique [0002] Sorghum belongs to the Gramineae Sorghum genus, an annual herb, and is one of the earliest cereal crops cultivated in China. Sorghum has high biological and economic yields, and has strong drought, waterlogging, and saline-alkali tolerance characteristics and adaptability. It can be planted in plains, hills, flooded depressions, and saline-alkali lands. It is a high-yield and stable crop. China's sorghum production is mainly grain sorghum, as well as sugar, feed and craft sorghum. Xinjiang has a temperate continental climate, with long and cold winters, short and hot summers, and dramatic changes in spring and autumn. Under normal circumstances, sorghum can only mature once a year, which belongs to the early and mid-maturation area of ​​spring sowing in the no...
