Description
Technical field
It is complete with corn more particularly, to an a kind of film 2 years the present invention relates to dry land agriculture crop fertilization method and technology field
Fertilising operation method under film double-furrow film.
Background technology
Corn full film double-furrow planting technology is that Gansu Province grows up on the basis of traditional film-mulching technique by mulch film
Cover and plant the item collection rain, soil moisture conservation and the drought resisting new technology that are combined with furrow.In recent years, with full film double-furrow planting technology
The popularization of large area, corn in Gansu full film double-furrow show-how popularizing area reaches 7.3 × 105hm within 20122More than, with
And application, the cost recovery of mulch film that comes also constantly is rising, to save operating cost, reduce dirt of the waste mulching film to farmland
Dye, it is double that agricultural science and technology worker has explored the full film of " use of film 2 years " corn on the basis of corn full film double-furrow planting technology
Furrow cropping pattern.
" film 2 years with " corn full film double-furrow cropping pattern its be mainly characterized by：In First Year full film double-furrow corn
After harvest, stalk is cut and is covered on mulch film, protect mulch film, mulch film should not be scratched, make mulch film complete, and note winter not
Allow livestock to eat stalk and damage mulch film；Second Year broadcasts the last week and transports stalk, with fine earth feud film breakage；It is wrong during sowing
Last year planting hole is opened, program request is punched by former spacing in the rows.Because the technology is that overlay film is utilized for 2 years, it is possible to decrease plow, site preparation, plane
Corn stubble, spreading etc. are manually put into；Effectively mitigate soil surface wind erosion, suppress winter-spring season soil water evaporation so that the winter
Spring, sustainable protect stored soil moisture；Early spring ground temperature is improved, strengthens the activity of microorganism, last year corn stubble is directly gone back after rotting
Field, improves soil physical and chemical property, increases soil fertility；But simultaneously there is also drawback and restriction, due to being 2 years use of a film, double ridges
Planting bed is all covered by mulch film when Second Year is sowed, therefore the fertilising of field kind bed soil earth is to restrict this agronomic technique
The key factor of popularization and application, will directly influence demand of each stage of corn growth to fertilizer nutrient, will be unfavorable for second
Year maize planting grows；Long-time covering with ground sheeting simultaneously does not connect, and planting bed can not obtain ploughing whole, and temperature strengthens micro- life under film
Thing also accelerates the growth of Field Pests while movable, growing way and health status for follow-up corn have a direct impact,
Finally it will all cause a film 2 years low and unstable with corn full film double-furrow agronomic technique relevant volume.
The content of the invention
An a kind of film is provided and uses corn full film double-furrow within 2 years it is an object of the invention to avoid the defect of prior art
Fertilising operation method under film, efficiently solves the problem of prior art is present.
To achieve the above object, the technical scheme taken of the present invention is：A described film uses corn full film double-furrow in 2 years
Fertilising operation method under film, is characterized in comprising the following steps：
1) cleaning of ridge face and furrow：After a film is terminated for 2 years with the sowing of corn full film double-furrow Second Year, it will remain
Crushing straw, cauline leaf in ridge face, furrow are removed, and need to avoid damage to sowing cavities and ridge body film surface in reset procedure；
2) activation of insecticide：3.2% abamectin emulsifiable concentrate and water are dissolved, ratio is 1:300~500；By 26% speed
Kill fourth missible oil to dissolve with water, ratio is 1:600~1:800；By the abamectin emulsifiable concentrate solution mixed with water respectively at 60 DEG C
Lower activation 6~8 hours；The sumicidin missible oil solution mixed with water is activated 4~6 hours at 40 DEG C respectively；
3) insecticide is sprayed：Insecticide sprays preceding first by 8% ethylene glycol according to 1:50~1:70 add, according to 30~
45 revs/min are stirred 3~5 minutes rapidly；Its both sides furrow is entered on the basis of double furrow micro-ridge bodies using knapsack sprayer
Row is sprayed, and is dried 2~4 days under natural environment；
4) fertilizer mixing is dissolved：Fertilizer needed for Maize at Seedling Stage is according to 60kg/ mus of urea, 80kg/ mus of calcium superphosphate, N/P ratio
1:0.6~1:0.8 carries out the matching of fertilizer, and solid fertilizer is fully mixed thoroughly, places 25~40 minutes；Corn toy trumpet mouthful phase institute
Fertilizer is needed according to 90kg/ mus of nitrogenous fertilizer, 110kg/ mus of potash fertilizer, potassium phosphorus compares 1：0.7~1：Dissolving for 0.9 progress fertilizer, solid-state is fertile
Material is fully mixed thoroughly, prevents caking, is placed 30~45 minutes；Fertilizer needed for the corn typhon mouthful phase is according to 120kg/ mus of nitrogenous fertilizer, potassium
Fertile 160kg/ mus, potassium phosphorus compares 1：0.5~1：Dissolving for 0.6 progress fertilizer, solid fertilizer is fully mixed thoroughly, prevents caking, is placed
50~70 minutes；
5) fertilizer applicator fertilising operation in the case where corn growth different phase completes film is used.
The insecticide solution that with the addition of ethylene glycol in described third step is according to 90~110L/hm2Sprayed.
The gait of march of fertilizer applicator in the 5th described step is 1.2~1.6km/h.
Fertilizer applicator in the 5th described step is bunch planting fertilization mode, Maize at Seedling Stage fertilising cavities and plant away from
From control in 10~15cm, fertilization depth is controlled in 3~5cm；Corn toy trumpet mouthful phase fertilising cavities is controlled with plant distance

Fertilizer is applied fertilizer according to 0.12~0.16kg/ caves；Fertilizer needed for the corn typhon mouthful phase is carried out according to 0.20~0.25kg/ caves
Fertilising.
Fertilizer applicator in described step 5 is to carry out fertilising operation in the furrow of micro-ridge both sides by fertilizer applicator, and fertilizer applicator is set
The lower-end front portion put in the direct insertion fertilizer applicator of full film double-furrow helical tooth sheave is connected with fertilizer delivering pipe.Described full film double-furrow spiral shell
The direct insertion fertilizer applicator of tooth socket wheel is revolved disclosed in Patents, and its patent No. is ZL201320646363.3, and patent name is
The direct insertion fertilizer applicator of full film double-furrow helical tooth sheave.
The beneficial effects of the invention are as follows：The fertilising operation method under corn full film double-furrow film of a described film 2 years, its
Can effectively solve the problem that a film is limited by for 2 years with corn full film double-furrow agronomic technique can not realize the bottleneck applied fertilizer under film, for this
The popularization of agronomic technique provides safeguard, it is to avoid do not attacked in a film with corn growing season under habitat conditions by insect pest within 2 years, and
There is enough fertilizer to meet corn different phase growth needs, by the fertilising side for applying different distance, different depth, different fertilizer amounts
Method improves corn emergence rate, increases crop yield effect.
