Screening Of Strawberry Planting Substrate Planting And Bioprotection Technology In Handan Area

At present,the strawberry planting mode in Handan area has gradually transformed from traditional soil culture to substrate culture with better fruit quality and higher yield.There are many problems in this process,including the large use of peat in the substrate will lead to a large consumption of this non renewable resource,which is contrary to the green concept of modern agriculture,and the use of strawberry in the process of planting due to pest control Medicament,which leads to the decline of food safety,also brings a series of environmental pollution problems.The experiment was carried out under this background,and the results were as follows:(1)The effects of different substrates on Strawberry Growth,photosynthetic pigment,fruit quality and strawberry yield were compared.The traditional planting media(peat: vermiculite: Perlite = 3:2:1)was set in the experiment,Four experimental groups were set up: PS1(coconut chaff: vermiculite: Perlite = 3:2:1),PS2(sapropelic soil: vermiculite: Perlite = 3:2:1),PS3(rotten chicken manure:vermiculite: Perlite = 3:2:1),PS4(rotten chicken manure: vermiculite: Perlite = 3:1:1),PS4(rotten chicken manure: vermiculite: Perlite = 3:1:1)The substrate of 3:1:1 of rotten chicken manure: vermiculite: perlite was used to plant strawberry,which not only improved the growth vigor,fruit quality and yield of strawberry,but also reduced the cost,saved resources,reduced the consumption of peat resources,and realized green and efficient production.(2)After studying the population dynamics of Tetranychus californica,the occurrence regularity was analyzed,and the effects of different degrees of insect pests on Strawberry Growth,fruit quality and yield were studied,and the harm degree to strawberry planting and production was analyzed.Finally,the control effect of different density of neoseimus californica on Strawberry Tetranychus and the influence on Strawberry Growth,fruit quality and yield were studied The results showed that the release of S.californica with a density of 21000 heads / 667m2 in strawberry cultivation could significantly improve the quality of strawberry and had a good control effect on Strawberry Leaf mite,which could be used in the control of strawberry spider mite in strawberry substrate cultivation.(3)In this paper,strawberry substrate cultivation was carried out by using the composted chicken manure: vermiculite: Perlite = 3:1:1,and the density was 21000 heads / 667m2.Under the premise of saving resources and cost,the production,quality and income of strawberry were significantly improved,which can be used for practical promotion.The results showed that the optimized cultivation mode had a significant effect on improving the quality of strawberry.It could be promoted in Handan area to reduce strawberry planting cost,save non renewable resources,reduce the occurrence and harm of diseases and insect pests,reduce land pollution,increase the income of strawberry farmers and enterprises,and provide high quality for consumers,safe and high quality strawberries.
