Embodiment Construction

[0015] The present invention is described in detail below

[0016] 1. Materials and methods:

[0017] 1. Test varieties: 5 late rice varieties were tested, namely Boyou 568, Toyotayou 981, Guoliangyou 7633, Longfengyou 139, and Meiyou 622. The above varieties are provided by Guangxi Guoliang Seed Industry Co., Ltd.

[0018] 2. General situation of the test field: The late rice test was conducted in 2014 in the farmer's responsibility field at the back slope of Shatian Village, Shatian Town, Fumian District, Yulin City. It has abundant water sources, convenient drainage and irrigation, and an area of ​​1354m2. 2 , formerly used as rice, the experimental field is a fertile sandy mud field, the soil pH value is 6.0, contains 2.72% organic matter, 0.15% total nitrogen, 0.07% total phosphorus, and 0.64% total potassium. The soil fertility is medium and uniform.

[0019] 3 Experimental design: There are 5 treatments in the test, each with 20m 2 , length 5m, width 4m, one treatmen...

Abstract

The invention discloses a difference-comparison technology method for breeding new late-rice varieties. The difference-comparison technology method is characterized by including the steps of variety selecting; land treating; fixed point well selecting; process operating and result screening. Well-bred varieties are selected and planted, and multi-spike sensitization-soft-rice high-quality hybrid rice varieties with the short spikes and the high maturing rate are obtained. The difference-comparison technology method has the advantages that land selecting is simplified, the scheme is new, field management is convenient, the method is reliable, careful selection and good breeding are achieved, the effect is obvious, the cost is low, and operating is easy.

Description

technical field [0001] The invention belongs to the field of agricultural technology, in particular to a process method of differentially contrasting and breeding new varieties of late rice. Background technique [0002] For many years, rice planting in the south has been randomly recommended by seed companies, which is extremely blind. It is hard work all year round, and the harvest is hit and miss. The yield is often low, the quality is poor, and rice lodging occurs from time to time. Contents of the invention [0003] The present invention provides a novel method, simple operation, low cost, quick effect, and a process method for breeding new varieties of late rice by comparison and comparison for optimal breeding in order to overcome the lack of science in existing rice planting and insufficient standardized management of paddy field soil and fertilizer. [0004] The technical solution of the present invention is like this: a kind of process method of the late rice new...
