Honghuagang District,Zunyi City,Guizhou Province,develops the characteristic industry of crispy peaches,and at the same time develops the forest economy and promotes the model of planting soybeans in peach orchards to promote rural ***,due to the different pests and diseases occurring in peach trees and soybeans,the control drugs used are also different,and the existing technology for spraying and controlling peach or soybean seedlings is operated separately and cannot be sprayed together at the same *** study,based on the actual situation of forest land,develops a spraying device for interplantation in forest(peach tree and soybean)from the aspects of technical solutions,working principles and beneficial effects,in order to solve the problem of low spraying efficiency of spraying control of peach tree or soybean seedlings in the existing technology.

Sustainable intensification of cropping systems is a strategy to increase productivity and reduce disservices of conventional ***[Camelina sativa(L.)Crantz]and field pennycress(Thlaspi arvense L.)are winter annual oilseed crops well suited to fill the fallow period between corn(Zea mays L.)and soybean[Glycine max(L.)Merr.]in the *** Corn Belt,but their inclusion may be limited by resource use limitations.A 2-year study was conducted from 2015 to 2017 in the *** Midwest to evaluate the effect of double cropping on winter oilseed crops and soybean productivity and economic *** included relay-and sequential-cropped soybean with winter camelina and field pennycress,and monocrop soybean as *** and grain yield of winter oilseed crops were not affected by cropping *** over years and cropping systems,winter camelina resulted in more biomass,nitrogen(N)uptake and grain yield by 240,186 and 139% respectively,compared to field *** biomass,N uptake and yield were higher in relay relative to sequential *** soybean resulted in similar total grain yield(soybean+winter oilseed crop)compared to monocropped *** cropping soybean could maintain net return compared to monocropped *** indicate that double cropping winter oilseed crops with soybean can be economically viable in the *** ***,research aimed at optimizing yield through N and water use while improving ecosystem services is needed.
