Biochemical soybean Seed
The present invention relates to a kind of auxiliary agent that the agriculture cultivation technology field is used, particularly a kind of biochemical soybean Seed.
Plant the clothing agent as a kind of novel agrochemical on the international market, meet the requirement of modern agricultural development.Plant the clothing agent and form, can directly or after dilution be wrapped in the surface of the seed, form pesticidal preparations with certain intensity and permeability diaphragm by effective ingredient, binding agent and other processing aid.In the world, seed coating technology research is used and is grown up over nearly more than 30 years.Japan calls seed coating technology " cornerstone that is agricultural foison ", the importance of visible seed coating technology.China's capsuled seed technology is started late, but application study and promotion rate are very fast, this be China's developing modern agriculture must select choosing.At present, the application of seed coating technology on cereal crops, economic crops, flowers, herbage and rare forest expanded just rapidly, also is the road important breakthrough that China's " seed engineering " is obtaining in recent years.
The agent of kind clothing meets the requirement of modern agricultural development.Advantage shows as 1, highly effective pesticide.Planting the clothing agent is a kind of highly effective pesticide, and it acts on the critical period of growth and development of plants, and the link that the insect growth is the weakest begins effectively anti-(worm) evil of curing the disease from plant roots, and control efficiency is better.2, economical convenient.Plant the clothing agent and be close to the surface of the seed, form the protection barrier, making on every side, insect is difficult to existence; and the efficacy of a drug is concentrated and is wrapped in around the seed; drug effect slowly discharges, the utilization ratio height, and other medicaments that do not need of dressing just can reach good control efficiency, reach the purpose of keeping a full stand of seedings.3, safe in utilization.The agent of kind of clothing adopts the high-tech technology to process, and uses advanced auxiliary agent, to seed safety, brings into play drug effect behind the seed pelleting among a small circle in, to atmospheric environment, soil environment is pollution-free, does not injure natural enemy.4, the lasting period is long.Owing to add advanced auxiliary agent in the process, after kind of clothing agent capsuled seed, agricultural chemicals can not spread to soil rapidly, but discharges slowly, is difficult for being affected by the external environment, and has improved the longevity of residure.5, be beneficial to sowing.The surface of the seed behind the dressing is smooth, is beneficial to mechanical planting, and seed coating medicine can be regulated the seed grain size simultaneously, improves mechanical planting efficient.
At present, seed coating technology has become the routine techniques that reclamation area, Heilungkiang soybean produces.Soybean can solve the following difficult problem of soybean in producing with kind of clothing agent dressing.1. the control seedling stage diseases and pests guarantees soybean germination rate, the latent root fly of control, first generation cyst roundworm, aphid, root rot, thrips and paraluperodes suturalis nigrogobilineatus.2. microelement-supplementing.Plant in the clothing agent and contain trace elements such as molybdenum, boron.3. raising crop yield.Through investigation, comparison is according to volume increase 5-10% behind the soybean dressing.
Chemical control technique: chemical control technique is very active frontier in the current research of agricultural science as a modern culture technique.It is different from traditional culture technique, is to regulate the Endogenous Hormones of doing in the object by growth regulator, thereby makes crop have better adaptability and resistance.In recent years, along with to improving the soybean per unit area yield and improving the attention of soybean quality, people have also carried out deep research to the soybean chemical control technique.People have used paclobutrazol (Wang Huayuan, 1992), myricyl alcohol (Zhang Di, 1985), ethrel (Grabau, 1991), 3-(2-pyridine radicals) propyl alcohol (Yao Haoran etc., 1985; Wang Gui etc., 1998) etc., all obtained certain effect.But these plant growth regulator or because residual serious (Liang Tianxi etc., 1993) or because that cost is too high, operation is difficult to grasp etc. is former thereby fail to promote.In recent years, along with rapid development of science and technology, new chemical control product is continually developed out.As strong Feng An is the plant growth regulator that develop in recent years China Agricultural University chemical control chamber, and application has obtained good effect (Yu Yunhua etc., 1997) on wheat; Seed dressing or foliage-spray can be controlled the soybean plant height effectively before soybean is broadcast, and improve the chlorophyll content of blade, can significantly improve soybean yields (Zheng Dianfeng etc., 1998; Permitted gorgeous etc., 1999).At present, it is also very general that uniconazole P is used, and it can cultivate soybean strong sprout, improves transplanting survival rate; Handle soya seeds with uniconazole P, can obviously promote soybean plant strain to downgrade and make its volume increase 15%-18% (Wang Huifang, 1998; Li Yuchang etc., 1998).New plant growth regulator chemical control No. 6 (China Agricultural University's chemical control center development) is seed dressing or initial bloom stage and branch phase foliage-spray prior to seeding, can improve the quality of soybean kernel, 8 seed amino acids of needed by human all improve in the seed, and wherein methionine obviously improves (Zhang Mingcai, 2001).This shows that the development of plant growth regulator is produced soybean with application and played important effect.
The microbial manure technology: in the current agricultural production, because the chemical fertilizer input amount increases year by year, fertilizer is residual increasing in the soil, not only causes the pollution of environment, and waste fertilizer, increases investment in agriculture.Go into bio-bacterial manure in the soil heavy dressing, can improve the availability of soil and fertilizer, alleviate contradiction in this respect.Popular in the market microbial manure mostly is phosphorus decomposing, separates the compound formulation of nitrogen and silicate-dissolving microbe.
At present, chemical control technique and seed coating technology have become two important means that improve output.But because the target that will realize is different, application all shows effect separately to chemical control technique separately with seed coating technology, and how with these two kinds of technological incorporation together, original difficulty realizes on producing.
Sustainable development has important function to the microbial manure technology for agricultural environment, but is significantly less than planned quantity because of the moisture discomfort usually causes bacteria containing amount in granular fertilizer.Someone made with kind of the test that the clothing agent mixes but can't be successful because of containing bactericide in kind of the composition of clothing agent.
Summary of the invention:
The objective of the invention is to solve the single problem of soybean kind clothing agent effect in the prior art, the invention provides a kind of biochemical soybean Seed, the agent of this kind clothing is the scientific and technological new product that integrates seed coating technology, chemical control technique and microbial manure technology, is the multi-functional compound formulation with up-to-date biochemical technology and seed coating technology combination.
