Description
Technical field
The invention belongs to salt-soda soil plant planting fields, the in particular to peanut of salt-soda soil peanut cultivation method and this method
Special fertilizer.
Background technique
The degree of self-sufficiency of my domestic vegetable oil is seriously (self-supporting lower than national strategy grain and oil safe-guard line less than 35% in recent years
Rate 60%).Peanut is the important oil plant industrial crops in China, expands peanut cultivation area, improves peanut total yield, national to ensureing
Grain and oil security strategy has a very important significance.According to incompletely statistics, the saline and alkaline land area in China about 1.0 × 107 hm2, account for
The 6.2% of cultivated area.The salt-soda soil cultivated area for expanding peanut strives ground contradiction to alleviation China's edible oil supply pressure and grain and oil
Have great importance.Delta Region of The Yellow River is one of main beach saline land in China, and there are about 3,000,000 mu of salt-soda soils to open
Kenli is used, if being used for the production of oil crops, the degree of self-sufficiency of China's vegetable edible oil will be greatly improved.
Peanut is happiness calcium crop, and interchangeability hypocalcia can seriously affect the development of peanut pod in soil, causes the underproduction.
And saline-alkali environment easily forms soluble low calcium or insolubility calcium compound, cause interchangeability calcium content substantially under
Drop.This seminar statistics indicate that, 5.0 g/kg of interchangeability calcium content average out on Dongying City Kenli County peanut cultivation ground, and mountain
The general high-yield field interchangeability calcium average out to 14.0g/kg of Dong Sheng.Meanwhile the core substance as Ca2+ oscillations transduction pathway, calcium ginseng
It is one of its important function to the response of adverse circumstance with regulation plant.Therefore the high yield of saline and alkaline tibet milkwort root, calcium nutrient environment to be realized
Improvement be important one of technical measures.
However, original salt-soda soil peanut cultivation belongs to blank, generally believe that peanut should not plant in salt-soda soil.In this regard,
The improvement of inventor's long campaigns beach saline land and research on utilization reduce salinity using big hydraulic pressure salt, increase acid organic fertilizer drop
Low PH, increasing slow-release fertilizer ratio prevents later period de- fertilizer, increases calcareous fertilisers and the anti-ghost of iron fertilizer and chlorosis, increases thickness of sowing and guarantee
The measures such as seedling rate can achieve the purpose of saline and alkaline tibet milkwort root high yield.According to many years experiment and demonstration situation, in moderate saline and alkaline condition
Lower plantation peanut be it is feasible, for years inventor Dongying Kenli salt-soda soil peanut cultivation realize 200 kilograms of large area/
Mu or more, cultivation technique is gradually perfect.
With going deep into for research, even if discovery applies enough fertilizer in salt-soda soil and is also impossible to reach the soil in high-yield field
It is required that how salt-soda soil peanut cultivation mainly draws away salt, then according to salt affected soil and peanut feature, research preparation salt-soda soil
Peanut cultivation method and salt-soda soil fertilizer specially for peanut.
Summary of the invention
Aiming at the problems existing in the prior art, inventor improves cultivation step, improvement and benefit in long-term beach saline land
On the basis of research, salt-soda soil is carried out and has kept away salt and add the research of microorganism formulation, purpose is for reducing seeding belt soil
Salt content, while improving microbial environment, increasing rhizosphere microorganism population and quantity, so as to improve Peanut Root System development, knot
Close the fertilizer specially for peanut on the implantation methods after traditional fertilization forms improvement, the life to the oil crops such as saline and alkaline tibet milkwort root are promoted
Production is of great significance.
Technical scheme is as follows:
A kind of salt-soda soil crop-planting method, after fertilising, "" shape cultivation, bandwidth 70-110cm, seeding belt centre shape
The ditch for being 8-12cm at wide and depth, avris form the ridge of high 10-20cm, the wide 15-25cm in bottom, line-spacing 35-55cm；Entirely
Broadband film-covering planting, but two avris in broadband respectively stay 3-10cm not overlay film, punch on ditch counterdie, simultaneously in ditch every 3-8cm
Earthing.
When the crop is peanut, then specific step is as follows:
(1) fertilizer specially for peanut is applied；
(2) ridging appearance: make "" shape cultivation, bandwidth 90cm, it is 10cm that seeding belt centre, which forms wide and depth,
Ditch, avris forms the ridge of high 15cm, the wide 20cm in bottom；
(3) peanut line-spacing 40cm, peanut row distance ditch medium line horizontal distance 20cm；
