Screening and testing method for cotton varieties suitable for mechanical harvesting

Abstract

The invention discloses a screening and testing method for cotton varieties suitable for mechanical harvesting. The method includes the following steps that climatic factors of a test region are analyzed, the growth cycle of cotton is combined, and the suitable sowing time is selected, so that the boll opening stage of the cotton is centralized in the clear and crisp season with few overcast and rainy days; according to the basic requirement for the agricultural technology of a cotton picker, the number of rows, the rowledge allocation model and the design density of test areas are determined; test sowing is carried out in an area form; standardized cultivation and management are performed during the whole growth cycle of the cotton; all the test areas are respectively harvested through the mechanical cotton picker; according to the difference, in the aspects of the yield, the fiber quality, the feature of resisting disease and pest in fields and the like, of the different cotton varieties and difference caused by compatible degrees of the different cotton varieties and the mechanical cotton picker, the mechanical picking cotton varieties more suitable for mechanical harvesting are screened. Through systemic investigation and inspection, the cotton varieties suitable for mechanical harvesting are screened more accurately, and the process of mechanized production of the cotton is accelerated.

Description

technical field [0001] The invention relates to the technical field of mechanized harvesting cotton, in particular to a screening and testing method for mechanized harvesting cotton varieties. Background technique [0002] About 30% of the world's cotton production is picked by machines, of which the United States, Australia and Israel are all countries in the world that have realized mechanized cotton picking, and Bulgaria, Greece, Kazakhstan, Kyrgyzstan and Spain have a cotton machine picking rate of over 70% . The United States was the first country to test and study mechanized harvesting. In 1975, the degree of cotton mechanized harvesting had reached 100%, ranking first in the world. [0003] Since 1996, the Xinjiang Production and Construction Corps began to carry out experiments on the introduction of cotton picking machinery and scientific research and development. After years of experiments and demonstrations, with the support of the state subsidy policy, the inves...

Problems solved by technology

[0005] It can be seen that the above-mentioned current test method of adopting machine-picked cotton mode cultivation and manual picking obviously has deficiencies, cannot fully reflect the characteristics of cotton varieties suitable for mechanical harvesting, and is not conducive to accelerating the steady development of cotton production mechanization, and urgently needs to be further improved.
