The abidance as a result of artificial charge on the high side, from the point of the artificial charge making a top this year, artificial charge every mus of 40-80 yuan differ, senior engineer price also causes a few farming labour to call an upsurge that earns money desperately artificially of course, end of the first ten days of a month reached together with in July the middle ten days of a month is consecutive high temperature weather, because make a top artificially,appear tired the phenomenon that dies in cotton field. Prep above of every mus of artificial charge that make a top is some closer in light of whole year, labor of together with farm is relatively nervous, partial cotton grower chose chemistry to make a top, namely save trouble saves interest again. Investigated since the middle ten days of a month in August, chemistry of partial cotton field hits an effect to fare badly, the phenomenon of occurrence reduction of output.
One, chemistry makes a top agent and the artificial effect that make a top is compared
Investigated A and B on August 10 two cotton field, a and B cotton field occupy cotton grower understanding, adjacent of ground date photograph, two cotton breed is consistent, 1 film 6 pattern are same, water fertilizer puts in time and dosage basic and identical, size of cotton boll peach agrees basically. Chemistry of A cotton field makes a cotton field, mu individual plant counts forteen thousand six hundred individual plant, mu the bell counts eighty thousand one hundred, group 94 centimeters tall, appearance nods liver mosses of fruit-bearing shoot of only individual plant to count 8 liver mosses, individual plant coping pours average sheet 1 become a bell with fruit-bearing shoot of 2 liver mosses 1; B cotton field makes a cotton field artificially, mu individual plant counts forteen thousand one hundred individual plant, mu the bell counts eighty-two thousand nine hundred, group 75 centimeters tall, appearance nods liver mosses of fruit-bearing shoot of only individual plant to count 6.5 liver mosses, individual plant coping pours average sheet 1 become a bell with fruit-bearing shoot of 2 liver mosses 2. From the point of investigation data, a cotton field relatively B cotton field mu total bell counts on the low side, rate of Cheng Ling of coping fruit-bearing shoot is low, although A cotton field compares liver mosses of fruit-bearing shoot of B cotton field,count much, but mu total bell number is small, a cotton field relatively reduction of output of B cotton field is inevitable. Make a top via enquiring A cotton field uses chemistry, from now on in light of cotton field, to coping the rate that become a bell brings huge influence, coping pours 3 liver mosses Cheng Ling rate is low, fall off serious. This likelihood and Yo period concerns climate and cotton earthnut this year.
2, reasonable use drug cannot blind
Chemical pruning makes technology carrying an agent on the head is systematization technology, chemistry makes the stand or fall of an effect that the agent uses, the water fertilizer government that gets cotton and change accuse a technology the influence is great. In last few years the chemistry of various experiment makes troops division a pruning agent, have model of form of pily individual plant commonly form and seal a top two kinds of medicine, namely inchoate model form agent is used when cotton of the first ten days of a month filled bud period hurried to change in June, went up in July again fruit-bearing shoot of the middle ten days of a month became enough undertake 2 times sealing a top, the fertilizer accusing water during and change accuse to be weighed particularly should. From the point of this year, cotton gives birth to Yo period to slant generally late 5-15 day, the artificial time that make a top relatively in former years also deferred 10 days or so, the last ten-day of a month in July reachs together with the first ten days of a month is consecutive in August the influence of high temperature, cotton bears a process to accelerate during, expression is centered to spend bell period and go up the phenomenon with fast peach, rate of Cheng Ling of fruit-bearing shoot of the upside in cotton is high, upside fruit-bearing shoot is opposite into bell circumstance in crop influence is great. If cannot master chemistry,an agent is hit to use a technology to will be affected to crop below the case with Cheng Ling brief this year period great. Use chemistry plays an agent cannot blind, choose relatively mature chemistry to play an agent, use chemistry twice to make a top, accuse water in time to accuse fertilizer, shrink section amine undertakes timely and right amount use cooperate. Must realising chemistry hits an agent to use a technology is a technology of assorted form a complete set, that segment gave an issue, huge influence chemistry plays the use effect of an agent, the treatment that asks science this technology. Hold to an experiment, set an example with promotion technology course, it is advisable that cotton grower mastered this technology to be popularized again.
3, the issue that makes foliaceous lotion
From calendar year chemistry the agent that make a top uses investigation to look, if cotton field controls bad individual plant model grow, bud of extremely easy fascicular gain a son-in-law in such a manner, or coping turn green grows 2 times, after playing foliaceous agent, coping is fascicular flocculus, or garrulous account other people, chemistry hits cotton field carrying an agent on the head to suggest later period must take seriously change accuse and prevent 2 times to lay chief problem. In the light of this kind of cotton field the proposal takes off foliaceous accelerate the ripening early, decrease machine impurity of shape of the garrulous when collecting.
Character, hard to avoid is extreme with inadequacy, if disagree to be asked with the proposal,communication leaves a message after article!
