Description
Technical field
The invention belongs to pesticide slow-release lagging material technical field, be specifically related to a kind of pesticide slow-release lagging material of containing chlopyrifos.
Background technology
China is production of bamboo shoots state maximum in the world, and along with the rapid expansion of Shoot bamboo cultivated area and the raising of intensive farming, in bamboo plantation, sick worm is caused harm increasing.Especially the popularization of Management Technology (upper soll layer covers other lagging material) is covered, while accelerating out bamboo shoot generation substantial economics by insulation, also to survive the winter to subterranean pest-insect due to insulation and provide good habitat, easily cause insect pest outburst after beginning of spring next year.Therefore current in bamboo shoots plantation, conventional method carries out spreading fertilizer over the fields granular pesticide (as Chlorpyrifos 94, Volaton) for 2 times in annual May and November (before covering) to prevent and treat subterranean pest-insect.
Because subterranean pest-insect mainly lives in the pedosphere of below 10cm, mainly on the bamboo shoots that bamboo Gen Bian district activity harm bamboo sub or slave bamboo whip director goes out.The granular pesticide used of upper soll layer mainly enters lower soil by rain effect and recurs and prevent the effect of subterranean pest-insect.But because covering material can produce crown_interception to rainwater, make the water yield that contacts with granule less, this leaching transition process is too slow, and amount is few, time when causing agricultural chemicals to enter into lower floor has missed the subterranean pest-insect hatching critical period, and quantity not sufficient is difficult to play good preventive and therapeutic effect to adult.The most key, the time that agricultural chemicals enters into lower floor goes out bamboo shoot peak period the beginning of spring exactly, adds agricultural chemicals enters bamboo shoots from soil near root whip risk by sorption.And current used granular pesticide is due to wherein containing some soil moved in improve the original composition, is easily brought in bamboo shoot ground by other pollutents such as heavy metal, nitrate, agricultural chemicals, thus pollutes bamboo shoots soil, cause potential threat to bamboo shoots quality safety; And may adventive be introduced, the shoot use stand edaphone comparatively closed is had an impact, affects the long-range business benefit on bamboo shoot ground further.
Rice straw is that current bamboo shoots cover one of lagging material conventional in operation, its abundance, cheap, and its have enrich micro-tubular structure, a large amount of agricultural chemicals can be absorbed by physisorption, become a kind of good pesticide slow-release material support, do not destroy again the heat-insulating property of himself simultaneously.If without creative work and a large amount of tests, those skilled in the art is difficult to accomplish Chlorpyrifos 94 and rice straw (or rice powder) to make a kind of materials application in pest control and being incubated in optimum mode.
Summary of the invention
For prior art Problems existing, the object of the invention is to design the technical scheme of the pesticide slow-release lagging material that a kind of containing chlopyrifos is provided.This material is used for bamboo shoots ground and covers and manage, can remarkable heat and moisture preserving, accelerates bamboo shoots and grows, go out bamboo shoot in advance and produce better effectiveness of operation; Simultaneously can by the slow releasing of Chlorpyrifos 94, such that agricultural chemicals can the subterranean pest-insect egg hatch phase just contacts with it in the winter time in time, enough, play prevention and control effect, and the harm of adult after the beginning of spring can be controlled by the longer lasting period; This material can not cause in bamboo shoots that objectionable impurities (agricultural chemicals, heavy metal, nitrite etc.) is residual to exceed standard, and is a kind of environmental protection shaped material.
The pesticide slow-release lagging material of described a kind of containing chlopyrifos, is characterized in that being made up of the component of following weight percent: Chlorpyrifos 94 1 ~ 10%, auxiliary agent 0.1 ~ 25%, carrier 50 ~ 90%, conditioning agent 0.1 ~ 25%.
