Abstract
The invention relates to a spring maize high-ridge thin-planting high-yield cultivation novel technology. The technology is characterized in that a purpose of realizing spring maize high yield is achieved through the processes of finely selecting seeds, selecting an appropriate plot, carrying out early sowing in advance, filling gaps with seedlings in time; carrying out fertilization and irrigation; carrying out castration in every other line; carrying out supplementary pollination, and controlling pests. The technology is suitable for spring maize high-yield cultivation.
Description
Technical field
The present invention relates to fruit-bearing forest seedling-raising technique field, specifically a kind of new technology of spring maize high ridge thin planting high-yield cultivating.
Background technology
Present many peasants generally adopt low ridge dense planting, and the proterties of good spring maize kind can not fully be showed, and have had a strong impact on increasing peasant income. Especially Dongdan 60, these improved seeds of No. 6, three Norths, mu is planted strain number can not exceed 3000 strains, and peasant planting exceedes 3000 strains mostly, even reaches 3500 strains, has caused land wastage.
Summary of the invention
The present invention is the technical problem that solves traditional spring maize low ridge dense planting, the new technology of inventing a kind of spring maize high ridge thin planting high-yield cultivating.
The present invention is for solving the problems of the technologies described above, the technical scheme of taking, and a kind of new technology of spring maize high ridge thin planting high-yield cultivating, its special character is to comprise following process:
1. elite seed, determine suitable plot: kind selects Dongdan 60, No. 6, three Norths, Dongdan 13, abide by and grind high-quality, the high-yield corn kinds such as No. 1, Lian Yu 16,20 grams of phoxims with 50%, to 10 kilograms of 400 grams of seed dressings of water, stir, to prevent and treat subterranean pest-insect, white ground broadcast in tune, will repeatedly harrow pressure the Spring Festival, accomplish defincienct in the upper and excessive in the lower, to keep soil moisture, soil moisture content deficiency should shift to an earlier date 2～3 days trench digging moisture creatings, after raking, waits to broadcast.
2, implantation methods. Broadcast front mu and execute thick fertile 3000 kilograms of high-quality, 15～20 kilograms of NPKs (nitrogen 16%, phosphorus 16%, potassium 16%); Early sowing while robbing, sowing on May 20～25, one broadcasts full stand; Weeding before bud. Ridge is high 25 centimetres, 0.5 meter of seeding row spacing, and seedling 2 strains are stayed in every cave, and mu is planted 2500～3000 strains of strain number, three leaf thinnings, six leaf final singlings, fill the gaps with seedlings in time. When 3～5 leaves of corn, spray corn gold and must find pleasure in 1 time, 7～11 leaves fill spray 1 time again, can make well developed root system, and internode shortens, and controls prosperous effective.
3, fertilising pouring. Before heavily impose jointing booting fertilizer after light, water and take root booting grouting water, 4～6 leaf phases are executed 10～15 kilograms of sulphur ammoniums in conjunction with the mu that waters, artificial cultivation uproot, and 10～12 leaf phase mus are executed 20～30 kilograms, urea, Synthetic worm, this phase, with 2～3 kilograms every mu of 3% phoxim granules, is spread on lobus cardiacus, control of maize snout moth's larva, 50～100 grams of 1500～2000 times of liquid of phoxim of available 50%, control two generations armyworm.
4. interlacing emasculation: in the time that just going out to push up, tassel carries out, and supple-mentary pollination.
Technique effect
Technique effect of the present invention is, adopts technique scheme, can realize the object of spring maize high ridge thin planting, and this mode convenient operation, has very good effect for High-yields of Spring Maize.
Detailed description of the invention
1. elite seed, determines suitable plot: kind is selected Dongdan 60 high-qualitys, high-yield corn kind, and 20 grams of phoxims with 50% are to 10 kilograms of 400 grams of seed dressings of water, stir, adjust and broadcast white ground, repeatedly harrow pressure the Spring Festival, accomplish defincienct in the upper and excessive in the lowerly, to keep soil moisture, after raking, wait to broadcast.
2, implantation methods. Broadcast front mu and execute thick fertile 3000 kilograms of high-quality, 15～20 kilograms of NPKs (nitrogen 16%, phosphorus 16%, potassium 16%), sowing on May 20～25, one broadcasts full stand, weeding before bud, ridge is high 25 centimetres, 0.5 meter of seeding row spacing, and seedling 2 strains are stayed in every cave, mu is planted 2500～3000 strains of strain number, three leaf thinnings, six leaf final singlings, fill the gaps with seedlings in time.
3, fertilising pouring. Before heavily impose jointing booting fertilizer after light, water and take root booting grouting water, 4～6 leaf phases are executed 10～15 kilograms of sulphur ammoniums in conjunction with the mu that waters, artificial cultivation uproot, and 10～12 leaf phase mus are executed 20～30 kilograms, urea, Synthetic worm, this phase, with 2～3 kilograms every mu of 3% phoxim granules, is spread on lobus cardiacus, control of maize snout moth's larva, 50～100 grams of 1500～2000 times of liquid of phoxim of available 50%, control two generations armyworm.
4. interlacing emasculation: in the time that just going out to push up, tassel carries out, and supple-mentary pollination.
