Abstract
The invention provides a wide-row double-tree planting method for planting corn. The method comprises the steps of land preparation, seed section, seedling planting, transplanting, field management, harvesting and the like, wherein the seed selection step comprises the following specific steps of: performing sealed seed pregermination on corn coated seeds until seeds sprout, and removing broken and rotten seeds which are not sprouted; the transplanting step comprises the following specific steps of: when seedlings grow to obtain two leaves and one core or three leaves, transplanting the seedlings to a large farmland, wherein a planting row distance is 90-100cm, the hill spacing is 35-40cm, and two seedlings are planted in one hill. According to the method, the row distance is increased, so that the ventilation condition is greatly improved, the solar energy utilization rate is enhanced, improvement of late-stage yield is promoted, field management is relatively convenient, and labor hours are saved; by use of a one-hill double-tree planting mode, the fertilizer utilization rate is improved, and the fertilizer consumption is saved; by virtue of sealed seed pregermination treatment, waste seeds are effectively removed, and the yield is ensured. The method is low in cost, simple to implement and easy to popularize and apply.
Description
Technical field
The present invention relates to corn planting field, the method particularly relating to the double; two strain maize planting in a kind of wide row one cave.
Background technology
Semen Maydis general planting such as widely uses at row or the wide-and narrow-row, it is common that line-spacing 66-75cm, spacing in the rows is 25-35cm, and density is many every mu of 2400-3000 strain.If publication number is the patent of 102138423A, disclose the narrow strain of a kind of wide row and the corn planting method of wide-and narrow-row equivalent dense planting.In existing method, thin planting and irrational dense planting are all the bottlenecks of restriction corn with high yield, and particularly Semen Maydis is when taking out hero, if illumination is not enough, corncob will bald point, cause the underproduction.
Summary of the invention
For deficiency existing in prior art, the method that the invention provides the double; two strain maize planting in a kind of wide row one cave.
For achieving the above object, present invention employs following technical scheme:
The method of the double; two strain maize planting in a kind of wide row one cave, comprises the following steps:
A, whole: selecting the non-salt sodium carbonate that crumb structure 30～50%, soil property are loose as land for growing field crops, deep plough 20～35cm, and carries out leveling process basal dressing；
B, seed selection: corn coating seed is carried out vexed kind of accelerating germination until dew mouth, reject not germinable seed broken, mildew and rot；
C, lower Seedling: the seed chosen is sown in nutritive cube and bow member, epiphragma；
D, transplanting: being transplanted to big Tanaka when seedling length to two leaves is wholeheartedly to SANYE, the line-spacing wherein planted is 90～100cm, cave is from for 35～40cm, each cave kind two strain seedling；
E, field management: Seedling grew to for 5～7 leaf periods, typhon mouth phase, pustulation period all carry out process of topdressing；
F, results: when plant leaf all turns yellow and starts withered, can gather in the crops.
Further, in described seed selection step, the method of vexed kind of accelerating germination is: capsuled seed is put into accelerating germination container, carry out spraying water and stirring, make all seeds all be stained with water and container bottom does not have hydrops, then by seed tiling and thickness of seed less than 10cm, then by gunnysack warm water soaking and wring out to not dripping, finally gunnysack is covered to capsuled seed, and every 3 as a child water spray 1 times.
Further, in described transplant step, the line-spacing of plantation is 93～97cm.
Further, in described transplant step, the line-spacing of plantation is 95cm.
Further, in described transplant step, the cave of plantation is from for 37～38cm.
Compared with prior art, the invention has the beneficial effects as follows:
1. the Semen Maydis density of reserved seedlings of the present invention exceedes the planting density of a conventional cave one strain pattern, and because of the increasing of its line space, penetrating condition is substantially improved, the increase of density between strain, given full play to crop aerobic, to the instinct of light, improve its blade extending transversely rate, its directed or primary orientation (blade with row to angle more than 45 °) rate may be up to more than 90%, it it is three times more than of a conventional cave one strain pattern, thus its Leaf positional distribution uniformity coefficient is substantially improved, greatly strengthen the efficiency of light energy utilization, promote the raising of later stage yield.
2. the present invention is with under the equal water and fertilizer condition of a conventional cave one strain pattern, and owing to configuring rationally, ventilation and penetrating light is good, straw toughness strengthens, and disease-resistant, anti-fall, insect pest alleviates, and later stage leaf color is dark green not to wane, pustulation period extends, and photosynthate substantially increases, and has promoted the volume increase of maize planting；And owing to configuring rationally, its disease pest and weed considerably reduces, it is simple to field management, and saving of labor economizes medicine.
3. the method can significantly improve utilization rate of fertilizer, one cave stays Seedling two strain to make planting density at 3300～4200 plants/acre, have 1650～2100 caves, and the planting density of a conventional cave one strain pattern is many every mu of 2400～3000 strains not etc., in every mu of special fertilizer 100 jin, conventional 0.0333～0.0417 jin of an every cave of cave one strain pattern, and 0.0476～0.0606 jin of every cave in the present invention, new model plantation significantly improves than the utilization rate of fertilizer of general planting, under every mu of premise using identical weight fertilizer, new model plantation plants many 0.0143～0.0189 jin of every cave fertilizer than normal mode.
4. the present invention can save dose, calculates with 0.03 jin of fertilizer often to spread manuer in holes, and in a conventional cave one strain pattern, 0.07 hectare needs 72～90 jin of fertilizer, and in the present invention every mu need 49.5～63 jin of fertilizer, save 22.5～27 jin of fertilizer.
5. the present invention can save man-hour, and in a conventional cave one strain pattern, every mu of 2400～3000 strains need 1.0 man-hours consuming time, and in the present invention, every mu of 1650～2100 caves need 0.8 man-hour consuming time, thus 0.2 man-hour is saved on every mu of ground.
6. the present invention by carrying out vexed kind of accelerating germination to capsuled seed, is not only effectively increased germination efficiency, and is conducive to proposing to cause ablastous seed because of broken, mildew and rot, it is to avoid phenomenon of being short of seedling occurs, it is ensured that yield.
Detailed description of the invention
Below in conjunction with embodiment, the technical scheme in the present invention is further illustrated.
