Abstract
The present invention provides a drought resistance and production increasing compound agent, which relates to a water retention agent for processing seeds before seeding or planting. Aiming at the characteristics of low crop yield in the arid regions of northern China, the present invention provides a drought resistance and production increasing compound agent for changing the distribution ratio of soil moisture and seed moisture, changing interior physiological adjustment and control and strengthening the capacity of crops for resisting adverse situations to reach the goal of drought resistance and yield increase. The drought resistance and production increasing compound agent of the present invention is prepared by mixing resin with high water absorption, KNO3, H3BO3, dispersing agents and other components. Through tests for many years, the yield of seeds processed by the drought resistance and production increasing compound agent of the present invention is increased by 15 to 20% higher than that of unprocessed seeds. The drought resistance and production increasing compound agent of the present invention has the advantages of simple process method and low cost (per mu approximately needs 2 Yuan).
Description
The present invention relates to sow or plant the water-loss reducer of pre-treatment seed.
The northern many places of China are in arid or semiarid zone, most of farmland non-irrigated condition, and inequality precipitation the fraction of the year, and variability is big, concentrates summer, and spring drought is serious, and the title that hits by drought 9 years out of 10 is arranged, and the dry farming management level still is in the state of " living at the mercy of the elements ".The particularly annual crop seeds of sowing when the serious time of spring drought just is unearthed, and does not have rainwater, and soil becomes dry gradually, makes seedling withered and yellow, causes the extremely low phenomenon of output.As everyone knows, super absorbent resin is the new product that occurs the eighties, it can absorb the pure water of deadweight hundreds of times and even thousand times, because intramolecule spacial framework effect, even can not be under certain pressure with moisture from coming out, water retention property with high-quality, just because of it has suction, these two kinds of particular performances of water conservation, some research unit directly acts on crop seeds with it and obtains good drought resisting effect, but because super absorbent resin is transparence, water insoluble and organic solvent, therefore, do not absorbed independent the use, do not directly act on the inner biochemistry of seed by seed, physiology course, and also have the uneven problem of seed pelleting.In addition, K
+Not participating in organic composition in plant corpus inside, is the activator of plurality of enzymes in the metabolic process, so regulate multiple metabolic process, K
+Stomatal movement there is regulating action, strengthens suction and the water retention of plant, improve the drought-resistant ability of plant; And B can the irritation cell film proton pump, make the cell membrane hyperpolarization, increase cell to K
+Absorption.Simultaneously, B can strengthen the photosynthesis of leaf, promotes the synthetic transportation and the accumulation of carbohydrate, impels well developed root system and crop precocity, as seen, and K
+With the synergy of B, just can reach the effect of combating drought and raising yields.
The present invention seeks to according to the above problem, utilize other chemical substance of super absorbent resin to mix a kind of drought resisting type coating agent for seed is provided, change the regulation and control of soil and seed (between seedling) moisture allotment ratio and internal physiological, thereby strengthen the ability of crop opposing adverse circumstance, reach the purpose of combating drought and raising yields.Product of the present invention acts on seed and acts on the seed effect with the macromolecule water uptake resin separately and is significantly improved, and cost reduces, and seed pelleting is even.
The object of the invention realizes being finished by following mode:
The present invention is by polyacrylic acid, KNO
3, H
3BO
3,
, dispersant mixes at normal temperatures, wherein polyacrylic acid account for 15～19%, KNO
3Account for 1～4%, H
3BO
3Account for 9～18%,
Account for 0.4～0.8%, dispersant accounts for 59.2～74.6%; Dispersant refers to ash.
The present invention is widely used in plant, particularly wheat, broom corn millet.The present invention is used to sow preceding preliminary treatment seed, under the more serious condition of spring drought, still can keep higher emergence rate, increase root/shoot ratio, increase biomass, strengthen the water absorbing capacity of root system and the moisture capacity of plant, physiological metabolism process in the regulation and control plant corpus is through test for many years, the seed that uses the present invention to handle reaches 15～20% with the untreated volume increase of comparing, processing method of the present invention is simple, and is with low cost, and every mu increases by 2 yuans approximately.
The invention will be further described by the following examples: embodiment:
Be applicable to a kind of drought resisting type coating agent for seed of wheat
Proportioning is as follows:
Polyacrylic acid (adopt Beijing Chemical Research Institute produce polyacrylic QB800 type) accounts for 19%, KNO
3Account for 2%, H
3BO
3Account for 9%,
Account for 0.5, dispersant accounts for 69.5～74.6%; With each above-mentioned medicament crushing screening,, mix in proportion and get final product generally more preferably greater than 60 orders.During use that the surface of the seed is moistening, be sprinkled into the complexing agent for preparing, stir, join even.Seed after treatment can directly be sowed or place standby.During use, the complexing agent consumption accounts for 6% of seed weight.Use coating agent for seed that said ratio makes in Wuchuan County, the Inner Mongol through test (this test region is non-irrigated condition all the year round) for many years, this technology is to improving seed germination and growth of seedling and remarkable to improving and improve some index effects that form output, average every mu with do not use the coating agent for seed wheat seeds compare the volume increase 15～20%, the rate of growth 8.7% of comparing with independent use polyacrylic acid.
