Abstract

The invention discloses an application technology of pre-emergence soil treatment herbicide used in a cornfield and belongs to the technical field of pesticide application. The corn pre-emergence soil treatment herbicide spraying is a conventional technical measure in corn high-yield culturing technologies and plays a key role in the high yield and stable yield of corns. A conventional application method of this type of herbicide is a liquid chemical spray closed method which has the defects of being high in manpower cost spent in spraying pesticide, low in working efficiency, short in safe and effective use time and the like in actual application. For the defects of the conventional herbicide liquid spray closed method, dry coarse sand with the diameter ranging from 0.2 mm to 0.3 mm is selected, the usage amount per mu is 2 kg, a proper amount of water is added to the herbicide per mu till the mixture reaches 300 g to be evenly mixed with the coarse sand with the water content smaller than 1%, the optimum soil condition is selected, and the chemical sand is evenly spread and applied in the field before weeds come up in the field. The corn pre-emergence soil treatment herbicide spraying has the advantages of being low in use cost, high in working efficiency and good in weeding effect and can be used safely and effectively both after corn sowing and before weeds come up after the corns come up, and the safe and effective use time of the herbicide is prolonged compared with the conventional method.

Description

Soil processing herbicide operation technique before a kind of corn field bud

Technical field

The invention belongs to technique in using agriculture chemical field, be specifically related to soil processing herbicide operation technique before a kind of corn field bud.

Background technology

Soil processing herbicide is sprayed before corn field bud, it is a routine techniques measure in maize high-yield culture technique, critical effect is played to corn with high yield, stable yields, in recent years along with the increase of labour's use cost, the cost of labor of corn field herbicide spraying is also in continuous increase, before corn field bud, soil processing herbicide uses conventional method is that medicine liquid spray closes method, and the weed killer herbicide that this method can only complete 10 mu of ground for each person every day after measured sprays work, and operating efficiency is on the low side.

Conventional medicine liquid spray is adopted to close method, weed killer herbicide uses before can only emerging after corn seeding, if used after emerging, easy poisoning is caused to corn, thus in production, the exercisable time is used safely short, and soil processing herbicide result of use affects very large before most of corn field bud by soil moisture, under higher soil moisture conditions, herbicidal effect is good, if soil moisture conditions is bad when using, herbicidal effect then can be made to be deteriorated, usually can run under current soil moisture conditions in actual production, herbicide spraying effect is bound to bad, but the corn of sowing will be emerged at once, and the awkward situation that sprays of having to.

The domestic and international research for soil processing herbicide operation technique before corn field bud at present, mainly concentrate on kind and best usage amount how to select weed killer herbicide, and in order to expand herbicide spectrum, improve preventive effect and mixed technical research etc. between the variety classes weed killer herbicide that carries out, for the operation technique research taking coarse sand as soil processing herbicide before carrier corn field bud, at home and abroad there is not been reported.

The object of the invention is to close method for the conventional medicine liquid spray of soil processing herbicide before corn field bud exist in actual production, the shortcomings such as spray medicine cost of labor is higher, inefficiency, use safety effective time are short, provide soil processing herbicide operation technique before a kind of brand-new corn field bud, to overcome the deficiencies in the prior art, for promoting that the development of Maize Production and the lifting of planting benefit provide technical support.

Summary of the invention

Technical scheme provided by the invention is as follows:

(1) the present invention take coarse sand as weed killer herbicide carrier, and select the particle diameter of coarse sand between 0.2 ~ 0.3mm, particle diameter is excessive, when spreading fertilizer over the fields, in unit are, sand grains quantity is few, affect herbicidal effect, particle diameter is meticulous not only affects the uniformity of spreading fertilizer over the fields also affects the distance that sand grains sheds, and reduces working efficiency.

(2) coarse sand selected is necessarily dry, and moisture is because controlling within 1%, and after the moisture coarse sand exceeded standard adds liquid, sand grains makes dispersed variation because moisture is too high, affect the uniformity that sand grains spreads fertilizer over the fields, thus affect herbicidal effect.

(3) mu coarse sand usage amount 2kg, consumption too much increases the labour intensity of operator, affects herbicidal effect by quantity not sufficient.

(4) added by the weed killer herbicide of mu consumption after mixing with the dry coarse sand of particle diameter 2kg up to standard after appropriate water reaches 300g, before weeds in field is not unearthed, field soil condition reaches after weed killer herbicide uses best requirement and spreads fertilizer over the fields medicine sand to field uniformly.

Good effect of the present invention is: use soil processing herbicide before corn field bud by this method, can significantly increase work efficiency, what can complete 100 mu of corn field weed killer herbicides after measured for each person every day spreads fertilizer over the fields task, for conventional medicine liquid spray closes 10 times of method operating efficiency, thus artificial use cost can significantly be reduced, because take sand grains as the carrier of weed killer herbicide, use after emergence of corn, also can natural landing even if there is sand grains to encounter maize leaves, poisoning can not be caused to maize seedling, thus extend herbicide safety effective service time, this method is adopted to use under the soil condition of the best by basic guarantee weed killer herbicide, thus the result of use of weed killer herbicide can be improved significantly, abridged edition, synergistic effect is obvious, for promoting that the development of Maize Production and the lifting of planting benefit provide technical support.

Embodiment

Select particle diameter dry coarse sand between 0.2 ~ 0.3mm, every mu of usage amount is after 2kg mixes with the weed killer herbicide liquid 300g containing mu consumption, before weeds in field is not unearthed, field soil condition reaches after weed killer herbicide uses best requirement and spreads fertilizer over the fields medicine sand to field uniformly.

Claims

1. soil processing herbicide operation technique before corn field bud, is characterized by:

(1) the present invention take coarse sand as weed killer herbicide carrier, the particle diameter of selection coarse sand will between 0.2 ~ 0.3mm, particle diameter is excessive, when spreading fertilizer over the fields, in unit are, sand grains quantity is few, affect herbicidal effect, particle diameter is meticulous not only affects the uniformity of spreading fertilizer over the fields, and also affects the distance that sand grains is shed, and reduces working efficiency.

(2) the necessarily dry moisture of the coarse sand selected should control within 1%, and after the moisture coarse sand exceeded standard adds liquid, sand grains makes dispersed variation because moisture is too high, affect the uniformity that sand grains spreads fertilizer over the fields, thus affect herbicidal effect.

(3) mu coarse sand usage amount is 2kg, and consumption too much increases the labour intensity of operator, affects herbicidal effect by quantity not sufficient.

(4) weed killer herbicide mu consumption is added after mixing with the dry coarse sand of particle diameter mu consumption up to standard after appropriate water reaches the weight of regulation, before weeds in field is not unearthed, soil condition reaches after weed killer herbicide uses best requirement and spreads fertilizer over the fields medicine sand to field uniformly.
