Abstract
The invention discloses a kind of accurate breeding methods of short season cotton new varieties, are related to agricultural plantation technology field.The present invention establishes Germplasm Resources, carries out field test, laboratory testing the following steps are included: collection and introduce all kinds of germ plasm resources.Wherein, in 100 parts of Germplasm Resources plant cotton strain, in a row, row is 10 meters long, 1.2 meters wide for each strain kind；The 1st identification is carried out at the existing florescence in the florescence of cotton, identifies strain 20 for blooming earliest；2nd identification is carried out to the early blow-of-cottons character that the existing florescence is in the term of opening bolls that earliest preceding 20 strains carry out cotton, identifies earliest strain 10 of blow-of-cottons；3rd identification is flower rate, yield, quality before the frost for measuring this 10 strains.The present invention is identified by three important periods grown to cotton plants, obtains satisfactory short-term cotton plant, has been ensured that the growth period of short-term cotton is synchronous and concentrates, has been conducive to the growth cycle for shortening plant.
Description
Technical field
The present invention relates to agricultural plantation technology field, specially a kind of accurate breeding method of short season cotton new varieties.
Background technique
The cultivation of short season cotton aims to solve the problem that current cotton planting industry recruitment is more, the low Cotton Industry problem of comparative effectiveness.It is short
Season, cotton just referred to the season of growth relatively short cotton new type.It is the development needed according to market with agricultural production, in conjunction with
It is corresponding scientific and technical and generation.Since China cotton region is vast, just there is the ecotype in corresponding short season in different cotton regions.In north
Portion Exceptional early mature cotton region short season cotton is just used as spring cotton seed to plant.Yellow River basin cotton region be develop wheat cotton two it is ripe, using short season cotton 5 below the moon
Mai Long interplanting is carried out at the beginning of ten days to 6 months, Yangtze river basin cotton region is transplanted after wheat or summer sowing and Xinjiang cotton mechanization production
Short season cotton kind need to be used.
Short season cotton growth period of the plantation of existing Cultivating techniques disperses, and leads to that plant Cheng Ling is not concentrated, blow-of-cottons are not concentrated, no
Conducive to carrying out unified mechanized harvesting, and cotton growing stage is too long, is easy to appear the situation that grain and cotton strives ground, causes to make produce
Amount decline, land utilization ratio is low, thus the existing short season cotton growth stage dispersion and growth cycle it is too long be those skilled in the art need
Technical problems to be solved.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of accurate breeding methods of short season cotton new varieties, by multiple
Identification is oriented cultivation to cotton line, solves the problems, such as existing short season cotton growth stage dispersion and growth cycle is too long.
In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of short season cotton new varieties are precisely trained
Educate method, comprising the following steps:
SS01: collecting and introduces all kinds of germ plasm resources, establishes Germplasm Resources, carries out field test, laboratory testing.Its
In, in 100 parts of Germplasm Resources plant cotton strain, in a row, row is 10 meters long, 1.2 meters wide for each strain kind；
SS02: the 1st identification is carried out at the existing florescence in the florescence of cotton, identifies strain 20 for blooming earliest；
SS03: the early blow-of-cottons character for being in the term of opening bolls that earliest preceding 20 strains carry out cotton to the existing florescence carries out the 2nd
Secondary identification identifies earliest strain 10 of blow-of-cottons；
SS04: the 3 identification is flower rate, yield, quality etc. before the frost for measuring this 10 strains, according to flower rate before frost and
10 strains that the comprehensive agronomy character of kind is identified from the 3rd time choose 1-2 strain；
It should be noted that SS02~SS04 was identified precocial 3 critical periods of cotton.
Further, nitrogen element content is 195-202 mgs/kg of range, phosphorus element content in the Germplasm Resources
For 67-72 mgs/kg of range, nitrogen element content is 112-116 mgs/kg of range.
Further, cotton line spacing 1.2m two-by-two, cotton plants spacing two-by-two in each cotton line
0.33m。
The invention has the following advantages:
The accurate breeding method of short season cotton new varieties identified by three important periods grown to cotton plants,
Satisfactory short-term cotton plant is obtained, has ensured that the growth period of short season cotton is synchronous and concentrates, test point soil analysis is convenient for sieve
The plant with growth potential is selected, the growth cycle for shortening plant is conducive to, avoids the occurrence of the situation that grain and cotton strives ground, orientation sieve
The cotton line selected has the advantages that the term of opening bolls concentrates and growth cycle is short.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
Detailed description of the invention
