Effects of different mulching patterns on summer and autumn baby cabbage production in Yunnan Province
This study aimed to improve the yield and quality of baby cabbage in summer and autumn,and achieve cost saving and effi-ciency enhancement.The effects of three different covering methods on summer and autumn baby cabbage in Yunnan high mountain plateau were studied.Four treatments were set up:anti grassland cloth(A1),black plastic film(A2),colorless plastic film(A3),and open field(CK),and the effects of three thin cover methods on the growth,yield,and planting efficiency of summer and autumn baby cabbage in Yunnan high mountain plateau were analyzed.The soil temperature at the roots of A1,A2,and A3 increased by 1.0℃,5.0℃,and 2.4℃compared to CK,and the yield increased by 7.0%,5.2%,and 3.3%compared to CK.The planting efficiency in-creased by 14.8%,10.5%,and 3.5%compared to CK.Under high temperature and humid weather conditions in summer and autumn,compared with A2 and A3,A1 had a smaller increase in temperature,which could ensure the root temperature of baby cabbage while breathing and dissipating heat,without causing high temperature obstacles in the root of baby cabbage.A2 and A3 had a large increase in temperature,resulting in high root temperature and hindered growth.Compared with A2 and A3,A1 had significant differences in yield and planting efficiency.In conclusion,when planting baby cabbage in summer and autumn,it was advisable to choose anti grass-land cloth coverage to ensure soil moisture preservation and nutrient utilization,prevent water and nitrogen loss,and achieve the effect of inhibiting weed growth and increasing yield and income.
