Abstract
The invention discloses a planting method for increasing peanut yield. The planting method comprises the step of seeding, wherein two seeds are vertically planted in a seeding ditch in parallel, embryonic roots are downward, the butt seam of two cotyledons is parallel to a ridge, and two holes of peanut are seeded on the ridge in a staggered manner. According to the invention, by changing the seeding method of seeds, two cotyledons are parallel to the ridge after peanut seedling emergence, so that first pair of lateral branches grown from the cotyledon node are both vertical to the ridge, and are trim and consistent; and at the same time, peanut is planted on the ridge in the staggered manner, thus the formed colony structure is favorable to increasing light transmittance and gas exchange in canopy, increasing photosynthetic efficiency of the canopy and further increasing legume yield. Tests prove that by adopting the method to plant peanut, the peanut seedling emergence is advanced by 1-2d as compared with routine seeding, the CO2 concentration and light transmittance at the roots of the plants on the ridge are increased by 2.2-7.6% and 9.6-12.3%, respectively, the photosynthesis intensity of the canopy is increased by 8.7-12.8%, and the legume yield is increased by 8.7-13.4%. Therefore, the planting method can obviously increase peanut yield.
Description
Technical field
The present invention relates to a kind of kind method for planting that improves peanut yield, belong to agricultural technology field.
Background technology
At present, traditional peanut tectorial planting type is that two seeds lie in the seed furrow at random, and peanut position, two caves is relative on the ridge.Though this seeding method is convenient, its peanut yield is desirable not to the utmost.Its reason: the one, emerging needs the time long, the prominent first downwarping in back of breaking in the seed coat of seed base-root, growth downwards then; And two cotyledons need transfer erectility (radicle down) to by level in soil, and both time-consuming of this process consumes nutrient again; Cause and emerge slowly; A little less than the back seedling growing way of emerging, and the regularity of emerging is poor, has directly influenced later colony quality.The 2nd, the pod seat life of peanut more than 70% is on first pair of side shoot, and the first pair of side shoot bears from the cotyledonary node of peanut seed, and the orientation of cotyledon has determined the orientation of first pair of side shoot; If with cotyledon abutment joint and ridge-direction parallelism, then first pair of side shoot is vertical with the ridge, so not only can make peanut envelope row ahead of time; Make colony accept more luminous energy; And make the whole colony unanimity that is evenly distributed in the field, and help colony's inner ventilation printing opacity, improve photosynthesis.Back two pairs of side shoot directions are at random and the conventional seed planting method is emerged, and cause plants stems branch skewness on the ridge, influence the canopy ventilation and penetrating light.In addition, the contraposition sowing is unfavorable for that also colony evenly distributes.
Summary of the invention
To above-mentioned prior art, the invention provides a kind of kind method for planting that improves peanut yield.
The present invention realizes through following technical scheme:
A kind of kind method for planting that improves peanut yield comprises sowing, during sowing, two seeds is stood upright in the seed furrow side by side, and radicle and makes two cotyledon abutment joints and ridge-direction parallelism down, two cave peanuts dislocation sowings on the ridge.
The present invention is through changing the type of seeding of seed; Make peanut emerge back two cotyledons and ridge-direction parallelism, the first pair of side shoot orientation that bears from cotyledonary node like this and ridge be to vertical, neat and consistent; While wrong bunch planting kind on the ridge; The group structure that forms like this helps improving canopy iuuminting rate and gas exchange, improves the canopy photosynthetic efficiency, and then improves pod output.Through evidence, adopt the peanut of method plantation of the present invention, peanut is emerged and has been shifted to an earlier date 1～2 day than conventional seed planting, plant base portion CO on the ridge
2Concentration and light transmittance have increased by 2.2～7.6% and 9.6～12.3% respectively, and the canopy photosynthetic intensity has improved 8.7～12.8%, and pod has increased production 8.7～13.4%.It is thus clear that of the present invention kind of method for planting can obviously improve the output of peanut.

Embodiment
Below in conjunction with embodiment the present invention is further described.Among the embodiment not the content of detailed description be routine techniques.
Sowing on April 28, seeding method:
Experimental group: during sowing, two seeds are stood upright in the seed furrow side by side, radicle 2 and makes two cotyledon abutment joints 1 and ridge-direction parallelism (like Fig. 1, shown in Figure 2), two cave peanuts dislocation sowings (as shown in Figure 3) on the ridge down.
Control group: adopt traditional seeding method, two seeds lie in the seed furrow at random, on the ridge peanut position, two caves relative (as shown in Figure 4).
All the other condition experiment groups are identical with control group, experimental field row spacing 85cm, and ridge face width 55cm broadcasts two row peanuts on the ridge, and at a distance of 30cm, the cave is apart from 16.5cm, two seeds in every cave, spring sowing plastic-film-covered cultivation.Kind is that plain edition major peanut flower is educated No. 22.
Result: contrast plant base portion CO on date of emerging, ridge of two groups
2Concentration, light transmittance, canopy photosynthetic intensity and pod output, as shown in table 1.Table 1 is the result show, the experimental group peanut was emerged 2 days in advance, plant base portion CO on the ridge
