Abstract

The invention discloses a kind of salt-soda soil high yield cultivation method of peanut, it is characterized in that: ridging, row spacing 42～45cm, the high 20～25cm in ridge, ridge face width 15～20cm; Overlay film on ridge, the wide 42～45cm of furrow, broadcasts two row peanuts in furrow, the line-spacing 32～35cm of this two row peanut. The present invention has realized the plantation of peanut in salt-soda soil, make peanut arable layer salt content in salt-soda soil reduce by 23.0%～28.8%, per plant number can improve 10.6～16.0%, kilogram fruit number reduce 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

A kind of salt-soda soil high yield cultivation method of peanut

Technical field

The present invention relates to a kind of salt-soda soil high yield cultivation method of peanut, belong to agricultural planting technique field.

Background technology

The soil salinization is the serious problems that affect agricultural production and ecological environment. The whole world approximately has 50% arable land to be subject to salt stress harm, and China's salt-soda soil area reaches 1,500,000,000 mu. Peanut is the main oil crops of China and industrial crops, along with the increase of population, and the increase of demand, the continuous decline of cultivated area, grain and oil are striven 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 ridge, on ridge, broadcast two row peanuts, peanut line-spacing 35～40cm on ridge, between ridge, peanut interval 50cm, plants in salt-soda soil according to this kind of mode, output is extremely low, cannot normally cultivate.

Summary of the invention

For solving deficiency of the prior art, the object of the invention is to provide a kind of salt-soda soil high yield cultivation method of peanut.

The present invention is for achieving the above object, and the technological means adopting is: a kind of salt-soda soil 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 ridge, the wide 42～45cm of furrow, broadcasts two row peanuts in furrow, the line-spacing 32～35cm of this two row peanut.

Operation principle: utilize migration rule and the peanut salt tolerant feature of salt in soil, change plantation on ridge traditional peanut at the bottom of ridge plantation, and then alleviate the saline and alkaline harm to peanut, improve salt-soda soil peanut yield. Ridging can induce salinity to rise in ridge, reduces salt content in furrow. The effect of covering with plastic film, the one, collection rain is pressed alkali, while raining, due to ridge face covering with plastic film, rainwater drops down in ditch along mulch film, can play the effect of pressing salt, the 2nd, the heating effect of mulch film can guide in soil moisture and move, also salinity is taken in ridge, the salt in soil is more focused on ridge, reduce salt content in ditch simultaneously; The 3rd, the effect of mulch film heat and moisture preserving, is conducive to the healthy and strong fertility of peanut, improves salt tolerance.

Beneficial effect of the present invention is: realized the plantation of peanut in salt-soda soil, make peanut arable layer salt content in salt-soda soil reduce by 23.0%～28.8%, per plant number can improve 10.6～16.0%, kilogram fruit number reduce 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%.

Brief description of the drawings

Below in conjunction with drawings and Examples, the present invention is further described.

Fig. 1 is planting structure distribution schematic diagram of the present invention;

Fig. 2 is the planting structure distribution schematic diagram of prior art.

Detailed description of the invention

A kind of salt-soda soil high yield cultivation method of peanut as shown in Figure 1, is characterized in that: ridging, row spacing 42～45cm, the high 20～25cm in ridge, ridge face width 15～20cm; Overlay film on ridge, the wide 42～45cm of furrow, broadcasts two row peanuts in furrow, the line-spacing 32～35cm of this two row peanut.

Example one

Test in 2011: planting patterns adopts the technology of the present invention: row spacing 43cm, the high 20cm in ridge, ridge face width 16cm, overlay film on ridge, the wide 45cm of furrow, broadcasts two row peanuts, line-spacing 35cm in ditch.

Prior art contrast: row spacing 90cm, the high 10cm in ridge, ridge face width 60cm, the wide 30cm of furrow, overlay film on ridge, broadcasts two row peanuts, line-spacing 40cm on ridge.

Table 1 result shows, with contrast peanut and compare, this invention can make peanut arable layer salt content in salt-soda soil reduce by 23.0%～25.3%, per plant number can improve 10.6～16.0%, kilogram fruit number reduce by 6.8～15.7%, plumpness and kernel percent improve respectively 2.6%～6.7% and 2.2%～3.5%, volume increase 30.4%～35.8%.

The impact of table 1 the present invention on 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 ridge, the wide 43cm of furrow, broadcasts two row peanuts, line-spacing 33cm in ditch.

Prior art contrast: row spacing 87cm, ridge face width 55cm, the high 12cm in ridge, the wide 32cm of furrow, overlay film on ridge, broadcasts two row peanuts, line-spacing 32cm on ridge.

Table 2 result shows, with contrast peanut and compare, this invention can make peanut arable layer salt content in salt-soda soil reduce by 24.8%～28.8%, per plant number can improve 13.8%～14.3%, kilogram fruit number reduce 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%.

The impact of table 2 the present invention on output economical character
