Abstract

The invention relates to a drought resisting water retention reducer and its usage. It comprises:30 to 60 percent weight of straw powder; 10 to 20 percent weight of water-loss reducer; 10 to 15 percent weight of film former; 20 to 40 percent weight of alta-mud; and 3 to 6 percent weight of bactericidal agent or biocidal agent. Wherein, the straw powder which includes 30 to 60 percent weight of straw, 1 to 3 percent weight of fertilizer, 1 to 3 percent weight of plant growth regulator and 120 to 140 percent weight of water, is made by agitation and dry disintegration at 60 to 70 centigrade degree;the water-loss reducer is high-absorbent resin; the film former is aggregated with 10 to 20 percent weight of acroleic acid and 2 to 4 percent weight of maleic acid. The invention is used in the drought resisting and water-loss of the seed, it comprises the following advantages: good air permeability, easy to degrade, no pollution to the environment; the seed absorbs nutrition slowly, extend the fertilizer effect. The operation is easy, the process flow is short, the cost is low, the energy consumption is small, and the preparing process doesn't bring environmental pollution problem.

Description

technical field [0001] The invention relates to a seed coating agent, in particular to a drought-resistant and water-retaining seed coating agent whose main component is plant fiber, and its application. technical background [0002] Seed coating technology is a practical technology developed in the past 30 years and widely used in agriculture, forestry and horticulture. In 1978, American scientists treated cotton seeds with a seed coating agent formulated with sorbose and adhesives, which effectively prevented cotton blight. In 1981, Soviet scientists researched and developed a seed coating agent that can form a thin film on the surface of seeds. When treating cotton seeds, sunflowers, corn, sugar beet and bean seeds, it not only played a role in killing germs and improving the germination rate of field seeds, but also It can properly advance the sowing period, thereby prolonging the vegetative growth period of crops and increasing crop yield. In 1982, the US Department o...
