The Variation of Soil Moisture and Fertility in Hot Pepper Drip-Irrigated under Plastic Sheet Mulch

Yu Fengyun(Regiment 21's Experimental Station,Agro-Reclamation Division 2,Hejing 841111)  
In order to understand the variation of soil moisture and fertilizer in hot pepper fields to make the best possible use of irrigation and fertilizer,this study was conducted at the agricultural experimental station in the south of Mount Tianshan.The results indicate that excessive amount of P and K fertilizers has been applied to hot pepper production.So the amount of N application should be kept unchanged,but those of P and K applied should be decreased to get the proper ratio N:P:K,i.e.,1:0.7:0.4.The volume of drip irrigation each time could amount up to 450 m3 water per hm2 and the total volume could be 5250 m3 water per hm2.
