平原沙区光、热、水、土资源丰富,适于一年两熟或多熟种植,而且由于砂土昼夜温差大,有利于糖分积累,是发展西瓜和花生等生产的良好基地。但是由于近年来西瓜种植面积的迅速扩大挤掉了大面积的春花生用地,如何利用间套复种的方式,改善由于西瓜生产周期短,冬秋地面裸露休闲,易受风沙侵袭的缺点,充分利用沙区的自然资源优势,发展花生等的生产是一个值得研究的问题。经过几年来的潜心研究和实践,粗细砂潮土区资源合理利用和保护型的新型种植方式“黑麦/西瓜/花生”油然而生。
The plain sandy area is rich in light, heat, water and soil resources, suitable for planting two or more crops per year. Due to the large temperature difference between day and night, the sand area is conducive to sugar accumulation and is a good base for the development of watermelon and peanut production. However, due to the rapid expansion of planting area of watermelon in recent years, squeezing a large area of peanut land, how to use intercropping multiple ways to improve the watermelon due to short production cycle, winter and autumn ground bare and easy to be affected by wind and sand invasion shortcomings, make full use of Sandy natural resources, the development of peanut production is a problem worth studying. After years of painstaking research and practice, the rational use of resources in the fine sand area and the new type of protection “rye / watermelon / peanut” came into being.
