Description
Technical field
The present invention relates to technical field of crop cultivation, more particularly to a kind of heavy salinized tibet milkwort root fertilizing method.
Background technology
Saline Land has become a global resources and environment problems, according to statistics, and global saline alkali land area is
Reach 9.55 × 108hm2, China's salinization of soil phenomenon is also increasingly severe, according to Educational, Scientific and Cultural Organization of state of the United Nations and grain farmer's group
Knit incomplete statistics, Chinese saline alkali land area about 9.91 × 107hm2, substantially all in state to be developed.The wherein Huanghe delta
4.43 × 105hm of regional wetland with saline-alkaline area2, the 70% of the soil gross area is accounted for, is the agriculture sustainable development in restriction this area
The primary factor of exhibition.Based on the stronger cotton of the salt resistance ability of plantation more than current area's moderate salt affected soil, but due to several years continuous cropping,
Soil productivity continuous decrease, pest and disease damage occur serious, and the cotton amount of labour used is big in addition, benefit continuous decrease, needs badly and finds out and cotton
Peanut is long-term, benefit is suitable and the replacement crop with good salt resistance ability.
Peanut is important oil crops and industrial crops, and peanut oil is one of main source of vegetable oil, and peanut is in
Critical role is occupied in state's agricultural development and foreign exchange earning.The consumption figure of China's edible vegetable oil is more than 10% with annual in recent years
Amplitude increase, imbalance between supply and demand be in aggravation gesture.With the gradually expansion of plant of grain crops area, oil crops make with grain
Thing strives the contradiction on ground.From the strong peanut varieties of salt tolerance are selected, while increasing the transformation of the middle-and-low-yielding fields such as salt-soda soil
With utilization, as one of replacement crop of saline-alkali soil area cotton, to expansion peanut cultivation area, improve pattern of farming and promotion agriculture
People's extra earning is significant, is also to ensure that China's edible oil vegetable oil is the certainty of efficient, high-quality and sustainable agriculture development safely.
Develop, improve, using nearly 1,300,000,000 mu of salt-soda soils, developing salt-soda soil peanut production, marched to salt-soda soil, being to ensure grain
The effective way of oily safety.Because peanut belongs to drought-enduring barren-resistant without Salt And Alkali Tolerance crop, current China's peanut salt-soda soil is rare
Peanut cultivation, or yield are very low.Therefore, in saline-alkali soil ecological region planting peanut, development space and have a high potential, be conducive to increase to spend
Agricultural climate condition for corn area, improves yield.
At present, the principal element that restriction salt-soda soil peanut yield is further improved is cultivated area limitation and agronomic measures section
The raising of skill level, improves peanut emergence rate, ensures that seedling full stand is neat, increase yield, be to expand wherein which kind of takes keep away salt measure
Salt-soda soil peanut production area, the important channel for ensureing saline and alkaline tibet milkwort root sustainable development.
According to this toward statistics and research, China's peanut area is at 80,000,000 mu or so, wherein 80% is distributed on poor rainfed land, salt
Alkali is on the ground almost without peanut cultivation.Its main cause, one is due to that peanut itself salt resistance ability is relatively low, is not belonging to salt tolerant crop,
More without the kind with stronger salt tolerance；Two be that saline-alkali soil area is more to plant based on Salt And Alkali Tolerance crop cotton, agricultural planting structure
It is single and more fragile, in addition during cotton expense of labour, and its cost increase in recent years, price, Benefit Drops；3rd, salt-soda soil flower
Raw fragmentary plantation, its cultivated area is small, and planting technology is immature, and what salt damage was caused be short of seedling, and disconnected ridge phenomenon is protruded, and yield is very
It is low, inferior quality.Therefore, cause that salt-soda soil peanut production area is small, technology is low, yield is unstable, economic benefit, Social Ecology
It is relatively low with ecological benefits.
Therefore, need that a kind of technical conditions of offer are easily controllable, method is simple and easy to apply, high yield badly in technical field of crop cultivation
Efficiently, with the low heavy salinized tibet milkwort root fertilizing method of stronger operability and raw material reusing, production cost.
The content of the invention
According to above the deficiencies in the prior art, the present invention provides a kind of heavy salinized tibet milkwort root fertilizing method, this method skill
Art condition is easily controllable, method is simple and easy to apply, high-yield and high-efficiency, with stronger operability and raw material reusing, life
Produce low cost, it is effective improve in, heavy salinized tibet milkwort root yield.
A kind of heavy salinized tibet milkwort root fertilizing method of the present invention, it is characterised in that：Soil is through pressure salt, the site preparation of pouring water
After fertilising, suitable peanut varieties and sowing opportunity are selected, film-covering planting mode, first after planting overlay film, sowing are made using flat
Mode uses double grains bunch planting way；
Wherein, described fertilising includes base manure and foliage spray, and described its fertilizer used of base manure is：Decomposed manure
5000~6000 kgs/acre, 40~50 kgs/acre of urea, 300~350 kgs/acre of general calcium, 3.0~3.5 kgs/acre of boric acid；
Described foliage spray is sprayed in fruiting period, and its fertilizer used is：Mass fraction is public for 0.7~1.0% urea liquid 50
Pound/acre, mass fraction be 0.2%~0.5% 50 kgs/acre of potassium dihydrogen phosphate, mass fraction be 0.5%~1.0%
50 kgs/acre of copperas solution.
In the present invention, the production of heavy salinized tibet milkwort root should pay attention to the administration of base manure, especially pay attention to high-quality decomposed manure,
The administration of calcium and magnesium fertilizer and boron fertilizer；Heavy salinized tibet milkwort root is easy to de- fertile early ageing, therefore increases foliage spray.
Wherein, preferred scheme is as follows：
Described pour water pressure salt, site preparation is followed the steps below：In the preceding progress prepartion of land of sowing, repair for pressing salt
Ridge ditch of pouring water, carry out fresh water irrigation pressure salt, make earth's surface keep 1~3cm water layer 2~3 days, soil moisture content to reach that soil is satisfied
And water content；After fresh water irrigation pressure salt, ploughed after carrying out soil after moisture evaporation.
Described fresh water, which is poured water, presses the irrigation quantity of salt for 150~170m3/ mu.
Described peanut varieties educate No. 25 for flower or flower educates No. 36, and the kind is Salt And Alkali Tolerance peanut varieties.
Described sowing opportunity is that 0~10cm ground temperature is more than 15~16 DEG C.
Seeding method makees planting patterns using flat, and peanut line-spacing keeps 28-30cm, and hill spacing 13-14cm, density is maintained at
1.65~1.85 ten thousand caves/mu, per bunch planting 2 seeds of kind.
Described film mulching method is every two rows peanut seeding overlay film, timely firming.
A kind of summary preferred scheme, heavy salinized tibet milkwort root fertilizing method of the present invention, can include following
Step：
1) salt site preparation is pressed：In carrying out prepartion of land before sowing, repairing ridge ditch of pouring water for pressing salt, fresh water irrigation pressure is carried out
