Note:According to NY/T1464《Pesticide field efficacy medicine test criterion》26th part:Cotton urges 4.4 cottons in withered dose of experiment Yield and quality investigation method is sampled test.
3 cotton of the present invention of table, which is planted, to be adjusted to cotton fiber quality improvement effect
Note:According to NY/T1464《Pesticide field efficacy medicine test criterion》26th part:Cotton urges 4.4 cottons in withered dose of experiment Yield and quality investigation method is sampled.
According to GB/T20392-2006《HVI Physical Properties of Cotton Fibres test methods》Carry out upper half mean length, neat Spend the measure of index, mic value, elongation and strength.
It can be seen from Table 1 that cotton of the present invention, which is planted to adjust, can effectively improve the blow-of-cottons rate of cotton and disleave rate.It compares Under, it is only capable of playing part defoliation effect, but blow-of-cottons effect unobvious only with Thidiazuron, and be only capable of playing only with foliar fertilizer Part blow-of-cottons effect, but defoliation effect unobvious.Thidiazuron and foliar fertilizer are used cooperatively by the present invention, in the original effect base of the two On plinth, blow-of-cottons and defoliation effect are further significantly increased, play significant synergistic effect, there is unexpected technology to imitate Fruit.
It can be seen from Table 2 that cotton of the present invention, which plants the application adjusted, can't influence output of cotton, can also play instead Part effect of increasing production.In contrast, individually it is unfavorable for increasing production using Thidiazuron, and the effect of increasing production that foliar fertilizer is used alone has Limit.Thidiazuron and foliar fertilizer are used cooperatively by the present invention, on the basis of the effect of increasing production of foliar fertilizer, overcome Thidiazuron to volume increase Adverse effect, play apparent effect of increasing production, play significant synergistic effect, have unexpected technique effect.
Cotton usually by mic value between 3.5-4.9, as normal mic value cotton, and mic value exists Cotton in the range of 3.7-4.2 is the more top grade cotton in normal mic value cotton.It can be seen from Table 3 that cotton of the present invention Hua Zhi adjustments can effectively improve the quality of gained cotton fiber.In contrast, Thidiazuron is used alone to gained cotton fiber Quality improvement effect it is limited, and foliar fertilizer is used alone, the quality of gained cotton fiber is had little effect.The present invention will Thidiazuron and foliar fertilizer are used cooperatively, and on the basis of Thidiazuron improves gained cotton fiber quality, are further significantly improved The quality of gained cotton fiber, plays significant synergistic effect, has unexpected technique effect.
Although illustrate and describing the present invention with specific embodiment, it will be appreciated that the above various embodiments is only used To illustrate technical scheme of the present invention, rather than its limitations;It will be understood by those of ordinary skill in the art that:Without departing substantially from this hair In the case of bright spirit and scope, it can modify to the technical solution recorded in foregoing embodiments or to wherein Some or all of technical characteristic carries out equivalent replacement;And these are changed or are replaced, and do not make the essence of corresponding technical solution It is detached from the range of various embodiments of the present invention technical solution;It is, therefore, intended that include belonging to the present invention in the following claims In the range of all these substitutions and modifications.
