河南省常年西瓜种植面积在12万公顷左右,辣椒种植面积在10万公顷左右,除少部分实行瓜、菜、粮、棉间作套种外,大部分茬口为小麦——玉米(大豆)——西瓜;西瓜——棉花——西瓜;西瓜——小麦——玉米等种植模式。这些传统的种植模式,在7月中下旬西瓜拉秧后,直到10月份播种小麦,有2个多月的时间造成土地闲置,致使该阶段较为丰富的光热资源白白浪费,导致农业生产率不高。我们在豫东商丘、开封;豫南的南阳、许昌;豫北的新乡、安阳等地,进行了不同瓜菜品种与不同种植模式的试验研究,其结果证明:西瓜地里套辣椒,在西瓜不减产的情况下,每667平方米地还可产辣椒3000～4000公斤,增收 The annual planting area of ​​watermelon in Henan Province is about 120,000 hectares and that of peppers is about 100,000 hectares. Most of the stubble crops are wheat-corn (soybean) -watermelon ; Watermelon - cotton - watermelon; watermelon - wheat - corn and other planting patterns. In these traditional planting modes, the sowing of watermelon seedlings in mid-to-late July and the sowing of wheat in October caused more than two months of land idleness, resulting in a waste of light and heat resources at this stage, resulting in a low agricultural productivity . We carried out experiments on different cucumber varieties and different planting patterns in Shangqiu and Kaifeng in the east of Henan; Nanyang and Xuchang in southern Henan; Xinxiang and Anyang in the north of Henan Province. The results showed that: Not cut the case, every 667 square meters can produce chili 3000 ~ 4000 kg, income
