夏季,气温高,雨量少,蒸发大,此时,又是西瓜、苹果、柑桔,茄子、番茄、辣椒、黄瓜等多种果蔬生长发育和结瓜、挂果的旺期。这时对土壤和环境要求严格,需求水肥多,管理稍有疏忽,产量、质量就会受到影响。大部分瓜果、蔬菜生长适宜温度为28—30℃左右,而6—8月份是一年中最热的时期,气温多在35—36℃以上,再加上雨少、蒸发大,无灌溉条件(特别是坡地、丘陵地、不保水的滩田)等因素的影响,往往使瓜果、蔬菜生长受抑,产量不高,质量差。若从5月底至6月上、中旬,在其行间铺草(麦秸、稻草、糠壳、青草、树叶等),在很大程度上可以改善其生长生态小环境,既可促进当茬高产增收,并可改良土 Summer, the high temperature, less rainfall, evaporation, this time, but also watermelon, apples, oranges, eggplant, tomatoes, peppers, cucumber and other fruits and vegetables growth and fruiting, fruiting period. At this time, the soil and the environment are strict, the demand for water and fertilizer is too much, and the management is neglected a little, the output and quality will be affected. Most of the fruits and vegetables grow at a suitable temperature of about 28-30 ℃, while June-August is the hottest period of the year, the temperature is more than 35-36 ℃, plus less rain, evaporation, no irrigation Conditions (especially on sloping land, hilly land, non-water-holding shoal) and other factors, often make fruits and vegetables suppressed growth, yield is not high, poor quality. From the end of May to the middle of June and the middle of the month, laying straw (wheat straw, straw, bran shell, grass, leaves, etc.) between its lines can largely improve its ecological environment for growth and promote crop yield Income, and can improve the soil
