Description
Technical field
The saving of labor that the invention belongs to agriculture production is fertile, relates to the dissolved fertilizer particle simultaneously containing weedicide, snail killing agent and Fertilizer nutrient, and spiral shell saving of labor fertilizer and production method thereof are killed in especially a kind of fertilization of rice weeding containing benzyl phonetic benzene thiophene acyl.
Background technology
China is large agricultural country, grain good harvest relation national well, grain-production is the infrastructural industries of national economy, paddy rice is the important food crop of China, its cultivated area accounts for 1/3 of plant of grain crops area, paddy ultimate production accounts for 45% of total output of grain, and the long-term cultivated area of current China, more than 4.2 hundred million mu, is one of country that world's Monitoring of Paddy Rice Plant Area and output are maximum.But the production of paddy rice, is subject to impact and the restriction of disease pest and weed, and wherein crop smothering is serious harm factor simultaneously.Between paddy rice and weeds, between different sorts weeds, competition is very fierce naturally, and they constantly fight for moisture in the space of paddy rice, air and soil and nutrition, to maintain the needs of respective g and D.It is reported: when Weedy Rice density is 1 strain/m
2rice Yield Loss Caused 9.15% can be caused, when Weedy Rice density reaches 7 strains/m
2time can cause Rice Yield Loss Caused more than 50%, Weedy Rice density reaches 12 strains/m
2time Rice Yield Loss Caused can up to 70%, crop smothering has a strong impact on rice yield.The medicament of preventing and controlling weed in rice field is more, efficient single dose is had also to have compound preparation, Common Herbicides has: benbbensulfuronmethyl, pyrazosulfuronmethyl, pentachloro-sulphur grass amine, cyhalofop-butyl, Butachlor technical 92, the third careless amine, quinclorac etc. and compound preparation thereof, but study carefully its effect, usefulness is weeding, function singleness.Applicant's research and development in recent years have the Weed removal medicinal fertilizer mixture of a series of fertilizing and weeding double effects, and functional had very large improvement and lifting.
But in practice, contriver finds that Fushou spiral shell has a strong impact on paddy rice seedling growth in early stage, has a strong impact on the volume increase good harvest of paddy rice, various places government is all in concern spiral shell evil problem.Fushou spiral shell Pomacea canaliculata, (Golden Apple snail), it is a kind of software harmful organism of exotic invasive, originate in South America Amazon River basin, behind invasion Guangdong in 1981, in Guangdong, Guangxi, Fujian, Yunnan, Zhejiang, Shanghai, multiple provinces and regions such as Jiangsu grow harm surely.Because its viability is very strong, breeding is fast, and within one month, can produce 1000-1200 grain ovum, specifically its place of laying eggs is on the water surface, and the cauline leaf usually along plant places ovum, can escape looking for food of natural enemy fish in water like this, guarantee that ovum is not inclined and go out.Therefore, control spiral shell evil is a great problem, and Fushou spiral shell has become the important harmful organism of the farm crop such as paddy rice, and it to the harm main manifestations of paddy rice is: gluttonous drinking water rice sprouts, causes paddy rice to be seriously short of seedling, directly affects output.It is reported, within 2006, national paddy rice injured area is more than 4,500,000 mu, and wherein the serious injured area of Guangxi late rice reaches 2,500,000 mu.On Guangxi Luzhai county and other places, the generation density of Fushou spiral shell in rice field is up to 16.95/square metre, and paddy rice strain rate of being injured is generally 7% ~ 15%, and high reaches 64%, and local reaches more than 90%, forms major disaster.Along with the continuous expansion of rice seedling throwing and live area, Fushou spiral shell is more outstanding to causing harm of paddy rice.
During traditional agriculture is produced, the spiral shell evil of paddy rice is based on chemical prevention, major pharmaceutical agent has niclosamide ethanolamine salt, the methaldehyde, sodium pentachlorophenate, triphen vinegar tin granula (TPTA) and tea bran etc., but its effect respectively has deficiency: niclosamide ethanolamine salt (Niclosamide ethanolamine), be a kind of there is stomach poison function kill the biological snail killing agent of software, stronger killing action is had to spiral shell ovum, schistosomicide etc., low to person poultry toxicity, but it degrades very fast in water, easily by adsorption by soil solid failure, holding effect is short; Though sodium pentachlorophenate has good molluscicidal effect to rice field Fushou spiral shell, there is restraining effect to rice seedling, have larger impact to environment and forbidden by National agricultural portion.At present, there is no the medicament being advantageously used in control rice field Fushou spiral shell, real paddy rice river snail evil is still very serious.
Along with the acceleration of national urbanization, Development of Urbanization, the adjustment of agricultural structure, people in the countryside, rural laborer shift to city in a large number; Along with the raising of labor shortage recruitment cost and the enhancing of " lazyboot's science " idea; agriculture production will to mass-producing, high efficiency, saving of laborization future development, and the mode of production of resource utilization of raising labour efficiency, improve and technical measures more and more will be subject to people and pay attention to.The existing resources of production of a kind of integration, make it paddy rice saving of labor having multi-functions fertile, meet the needs of national Industry Policy and modern agricultural production.In agriculture production, the product having multiple efficacies concurrently more and more becomes the new direction of means of agricultural production agricultural chemicals Enterprise product development.Research about Weed removal medicinal fertilizer for paddy rice is on the books in phase early 1960s; once the weedicide more than 300 that proposition can be mixed with fertilizer is planted; but there is the key technical problems such as quality uniformity, stability and application security in process of production; so the product realizing industrialization is few; China is also in the primary stage of research and development, and main products has applicant to research and develop and multiple Weed removal medicinal fertilizer for paddy rice of having accomplished scale production---land of happiness gold rice multi-product card series product.But pesticide herbicide, snail killing agent and fertilizer carrier being integrated and be applied to rice weeding, kill the correlative study of the medicine fertilizer of spiral shell and have not been reported, is also the technical barrier needing solution in current agricultural sciences badly.Through retrieval, about Weed removal medicinal fertilizer for paddy rice, snail killing agent, the patent documentation that kills spiral shell fertilizer have:
