近年来,吉林省双辽市花生种植面积逐年增加。为防止干旱、提高地膜覆盖花生的产量和经济效益,平洼沙壤土地被大量用于覆膜栽培花生。平洼地具有地温低、地下水位高、土质肥沃等特点。用地膜覆盖花生,增温效果显著且抗旱能力强,增产幅度大。由于每年雨水分布不均,平洼地地势较低,田间小气候特殊等原因,易发生烂果、落果等问题,从而 In recent years, the planting area of ​​peanut in Shuangliao City of Jilin Province has been increasing year by year. In order to prevent the drought and improve the yield and economic benefits of mulching with mulch, the sandy land in Pingwa is widely used for mulching and planting peanuts. Flat depression with low temperature, high water table, fertile soil and so on. Covering peanuts with mulch has significant warming effect and strong drought resistance with large yield increase. Due to the uneven distribution of rainwater every year, low-lying depression, special microclimate in the field and other reasons, prone to rotten fruit, fruit drop and so on
