Abstract
The invention discloses a high-yield method for cultivating peanuts in a saline-alkali land. The high-yield method for cultivating the peanuts in the saline-alkali land is characterized by comprising the following steps: ridging, wherein the ridge spacing is 42-45cm, the ridge height is 20-25cm and the ridge surface width is 15-20cm; laminating ridges, wherein the furrow width is 42-45cm; sowing two rows peanuts into each furrow at a row spacing of 32-35cm. By the high-yield method, the peanuts are planted in the saline-alkali land; the salt content of a peanut cultivating layer in the saline-alkali land is reduced by 23.0-28.8%; the fruit number per plant can be increased by 10.6-16.0%; the fruit number per kilogram is reduced by 6.8-15.7%; the full fruit rate and the kernel rate are increased by 2.6-7.3% and 2.2-4.7% respectively; the yield is increased by 22.4-38.9%.
Description
Technical field
The present invention relates to a kind of saline land high yield cultivation method of peanut, belong to the agricultural planting technique field.
Background technology
The soil salinization is the serious problems that affect agricultural production and ecotope.The whole world approximately has 50% arable land to be subject to salt stress harm, and China's saline land area reaches 1,500,000,000 mu.Peanut is the main oil crop of China and economic crops, along with the increase of population, and the increase of demand, the continuous decline of arable area, grain and oil are striven the ground contradiction, and how development and utilization salinization land resource has great importance.
Existing peanut cultivation mode is row spacing 85~90cm, ridge face width 55~60cm, high 10~the 12cm in ridge, the wide 30~32cm of furrow, overlay film on the ridge, broadcast two row peanuts on the ridge, peanut line-spacing 35~40cm on the ridge, peanut interval 50cm plants in the saline land according to this kind mode between the ridge, output is extremely low, can't normally cultivate.
Summary of the invention
For solving deficiency of the prior art, the object of the invention is to provide a kind of saline land high yield cultivation method of peanut.
The present invention is for achieving the above object, and the technological means that adopts is: a kind of saline land high yield cultivation method of peanut is characterized in that: ridging, row spacing 42~45cm, the high 20~25cm in ridge, ridge face width 15~20cm; Overlay film on the ridge, the wide 42~45cm of furrow broadcasts two row peanuts in the furrow, the line-spacing 32~35cm of this two row peanut.
Operation principle: utilize migration rule and the peanut salt tolerant characteristics of salt in soil, plantation is planted at the bottom of changing the ridge on the ridge that peanut is traditional, and then alleviates saline and alkaline harm to peanut, improves the saline land peanut yield.Ridging can induce salinity to rise in the ridge, reduces salt content in the furrow.The effect of covering with plastic film, the one, collection rain is pressed alkali, when raining, because ridge face covering with plastic film, rainwater drops down in the ditch along mulch film, can play the effect of pressing salt, the 2nd, the heating effect of mulch film can guide on the soil moisture and move, also salinity is taken in the ridge simultaneously, the salt in the soil is more focused on the ridge, reduce salt content in the ditch; The 3rd, the effect of mulch film heat and moisture preserving is conducive to the healthy and strong fertility of peanut, improves salt resistance.
Beneficial effect of the present invention is: realized the plantation of peanut in the saline land, make peanut plow layer salt content in saline land reduce by 23.0%~28.8%, the per plant number can improve 10.6~16.0%, kilogram fruit number reduces by 6.8~15.7%, plumpness and kernel percent improve respectively 2.6%~7.3% and 2.2%~4.7%, volume increase 22.4%~38.9%.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is planting structure distribution schematic diagram of the present invention;
Fig. 2 is the planting structure distribution schematic diagram of prior art.

Table 1 the present invention is on the impact of output economical character
Example two
Test invention technology in 2012: row spacing 45cm, the high 22cm in ridge, ridge face width 19cm, overlay film on the ridge, the wide 43cm of furrow broadcasts two row peanuts, line-spacing 33cm in the ditch.
The prior art contrast: row spacing 87cm, ridge face width 55cm, the high 12cm in ridge, the wide 32cm of furrow, overlay film on the ridge is broadcast two row peanuts, line-spacing 32cm on the ridge.
Table 2 is the result show, compare with the contrast peanut, this invention can make peanut plow layer salt content in saline land reduce by 24.8%~28.8%, the per plant number can improve 13.8%~14.3%, kilogram fruit number reduces by 2.9%~3.7%, plumpness and kernel percent improve respectively 4.7%~7.3% and 3.6%~4.7%, volume increase 22.4%~38.9%.
Table 2 the present invention is on the impact of output economical character
Comprehensive above-described embodiment can be found out, compare with the contrast peanut, the present invention can make peanut plow layer salt content in saline land reduce by 23.0%~28.8%, the per plant number can improve 10.6~16.0%, kilogram fruit number reduces by 6.8~15.7%, plumpness and kernel percent improve respectively 2.6%~7.3% and 2.2%~4.7%, volume increase 22.4%~38.9%.
