Description
Technical field
The invention belongs to technical field of crop cultivation, and in particular to the user of water-retaining agent in a kind of sowing of Drought Resistance in Peanut
Method, type of seeding and system.
Background technique
Arid be influence agricultural production an important factor for one of, China every year because 100,000,000,000 kg of drought and water shortage underproduction grain with
On, although it is drought-enduring plant that peanut is opposite, arid also can generate significant damage to peanut production.
Often by drought in Spring Peanut growth course, most of the northern region of China is broadcast in 3~May of spring for Spring Peanut
Kind season, and often there is spring drought in this period, there is the saying to hit by drought 9 years out of 10, often resulting in peanut is difficult to sow, or after planting
Because arid is difficult to emerge, therefore the sowing of northern area Spring Peanut just faces soil moisture content deficiency problem, always affects peanut stable high yield,
In recent years, although film-mulching technique is widely used in preserving soil moisture, it is improving water use efficiency
While also bring " white pollution ", be unfavorable for soil Substantial evaluation.Peanut production also has anti-using water-retaining agent realization
Drought production, but water-retaining agent is all the modes such as to apply by ditch spread, cave to realize that drought resisting produces mostly, so that the usage amount of water-retaining agent
It is excessive, it is inefficient, it causes greatly to waste, and the edaphic condition of the arid for soil water content lower than 40%, it should
The application of prior art water-retaining agent cannot effectively realize peanut rudiment and emerge.
The technical staff in arable farming field has been devoted to seek the various usage amounts that can reduce water-retaining agent, improves effect
The water-retaining agent application method of rate and the edaphic condition suitable for Extreme drought.104904539 A of Chinese patent literature CN discloses one
The method of kind of tea place drought-resistant water-preserving fertilizer conservation, disclose by inhale water saturated water-retaining agent tiling to deep 25cm, width 20cm ditch in, then
Covering soil makes the usage mode of the water-retaining agent concordant with ground, and the water-retaining agent drought resisting time long effect of the prior art is also suitable well
In the soil environment of Extreme drought, so it does not consider the design feature of peanut, and for only needing spring water conservation drought resisting to go out
For the peanut of bud, the mode for the water-retaining agent that tiles also results in the waste of great manpower, material resources and financial resources, and application efficiency is not also high.
Therefore there is an urgent need to a kind of greens, the utilization technology of high-performance water-retaining agent on peanut production, realize peanut in arid
Under the conditions of sow, and successfully emerge.
Summary of the invention
Therefore, the present invention is that overcome water-retaining agent usage amount in the prior art excessive, inefficient and do not have needle
The defect for specially designing the design feature of peanut the application method of water-retaining agent is provided and is retained in a kind of Drought Resistance in Peanut sowing

For this purpose, the invention provides the following technical scheme:
The application method of water-retaining agent in a kind of sowing of Drought Resistance in Peanut, is pressed into crannied peanut on shell for water-retaining agent aqueous solution
In fruit, then peanut shell is made to adhere to water-retaining agent powder, then peanut is sowed by treated.
The water-retaining agent includes the component of following parts by weight: 10-35 parts of polyacrylamide；40-80 parts of polyacrylate；Water
8-10 parts；0.5-1 parts of crosslinking agent；0-27 parts of starch.
The mass percent concentration of the water-retaining agent aqueous solution is 0.1~3wt%.
A kind of Drought Resistance in Peanut type of seeding, the application method comprising above-mentioned water-retaining agent.
The Drought Resistance in Peanut type of seeding, specific steps are as follows:
1) peanut is cooked into extrusion process, makes there is crack not destroy peanut kernels on shell；The method of the present invention sows peanut
Fruit needs to select that appearance is full, peanut without insect pest disease.
2) treated, peanut is fitted into negative pressure device, and water-retaining agent aqueous solution is added in container, liquid level is made to exceed flower
Fruit face；Vacuumize process extracts gas in peanut shell out, and pressure release is in water-retaining agent aqueous solution indentation peanut shell；
3) it pulls peanut out and is rolled in water-retaining agent powder, peanut shell is made to adhere to water-retaining agent powder；
4) by step 3), treated that peanut is sown into dry soil, earthing.
6, type of seeding according to claim 5, which is characterized in that vacuumize process pressure is 0.04 to 0.1Mpa, place
Manage 1~15min of time.
The equipment that extrusion process uses be peanut rejuvenator, the peanut rejuvenator be successively arranged from top to down feed hopper,
Squeezing tank, motor, the squeezing tank are the cabinet of upper end opening, and the horizontal both ends that are equipped with extend through squeezing tank in the squeezing tank
