Abstract
The invention relates to the technical field of fertilization for dry-land agricultural crops, and particularly relates to an all-film double-furrow under-film corn fertilization working method using a film for two years. The all-film double-furrow under-film corn fertilization working method comprises the following steps: (1) cleaning ridges and furrows; (2) activating insecticides; (3) spraying the insecticides; (4) mixing and blending fertilizers; and (5) carrying out under-film fertilization in the different growth phases of corn by using a fertilizer applicator. The all-film double-furrow under-film corn fertilization working method is capable of effectively breaking through the bottleneck of the limit that under-film fertilization cannot be realized by a corn all-film double-furrow agricultural technology using a film for two years, providing a guarantee for the popularization of the agricultural technology, and avoiding insect pest attack during a corn growth period in the habitat condition of using a film for two years; moreover, enough fertilizers meet the growth needs in the different phases of corn, and the corn emergence rate is increased and the crop yield effects are improved by applying fertilization methods with different distances, different depths and different fertilizer amounts.
Description
Technical field
The present invention relates to dry land agriculture crop fertilization method and technology field, especially relate to an a kind of film 2 years operational method of applying fertilizer under corn full film double-furrow film.
Background technology
Corn full film double-furrow planting technology is that Gansu Province grows up and plastic mulching and furrow planted of combining and collect rain, soil moisture conservation and drought resisting new technology on traditional film-mulching technique basis.In recent years, along with the large-area popularization of full film double-furrow planting technology, within 2012, corn in Gansu full film double-furrow show-how popularizing area reaches 7.3 × 105hm
2above, the application of thing followed mulch film, cost recovery are also in continuous rising, for saving operating cost, reduce waste mulching film to the pollution in farmland, agricultural science and technology worker explores on corn full film double-furrow planting technology basis " film 2 years with " corn full film double-furrow cropping pattern.
" film 2 years with " its main feature of corn full film double-furrow cropping pattern is: after First Year full film double-furrow harvest corn, being cut by stalk covers on mulch film, protects mulch film, does not scratch mulch film, make mulch film complete, and note not allowing winter livestock eat stalk and damage mulch film; Second Year is broadcast and is transported by stalk the last week, with fine earth feud film breakage; Stagger during sowing planting hole last year, by former spacing in the rows punching program request.Because this technology is that overlay film utilizes for 2 years, can reduce plow, whole, plane corn stubble, spreading etc. manually drop into; Effectively alleviate soil surface wind erosion, suppress winter-spring season soil water evaporation, make the sustainable guarantor of winter-spring season store soil moisture; Improve ground temperature in early spring, strengthen the activity of microorganism, the rotten rear direct returning to farmland of corn stubble last year, improves soil physical and chemical property, increases soil fertility; But also there is drawback and restriction simultaneously, owing to being a film 2 years use, two ridges kind bed is all covered by mulch film when Second Year is sowed, therefore the fertilising of field kind bed soil is the key factor that this agronomic technique of restriction is applied, by directly having influence on each stage of corn growth to the demand of fertilizer nutrient, growing of Second Year maize planting will be unfavorable for; Long-time plastic mulching does not simultaneously connect, planting bed cannot obtain cultivated whole, under film, temperature also accelerates growing of Field Pests while strengthening microbial activities, the growing way of follow-up corn and health status are had a direct impact, a film 2 years finally all will be caused low and unstable with corn full film double-furrow agronomic technique relevant volume.
Summary of the invention
The object of the invention is to avoid the defect of prior art and provide an a kind of film 2 years by operational method of applying fertilizer under corn full film double-furrow film, efficiently solving prior art Problems existing.
For achieving the above object, the technical scheme that the present invention takes is: a described film 2 years operational method of applying fertilizer under corn full film double-furrow film, is characterized in comprising the following steps:
1) cleaning of face, ridge and furrow: after a film terminates with the sowing of corn full film double-furrow Second Year for 2 years, the crushing straw remained in face, ridge, furrow, cauline leaf are removed, damage sowing cavities and ridge body face can not be avoided in reset procedure;
2) activation of insecticide: 3.2% abamectin emulsifiable concentrate and water are dissolved, ratio is 1:300 ~ 500; 26% sumicidin missible oil and water are dissolved, ratio is 1:600 ~ 1:800; The abamectin emulsifiable concentrate solution mixed with water is activated 6 ~ 8 hours respectively at 60 DEG C; The sumicidin missible oil solution mixed with water is activated 4 ~ 6 hours respectively at 40 DEG C;
