为解决我省西瓜生产中存在的产量水平低、高产不稳产、商品性能差、技术不配套等问题,开封市农科所于1987—1991年开展了西瓜优质高产栽培技术研究。现将西瓜优质高产栽培生产途径及主要技术指标、品种选择等总结于后。一、合理密植,协调个体与群体的关系通过对丰收二号高产优质西瓜的合理群体结构、生育规律等的研究表明,结果数与产量呈显著正相关,单瓜重与产量相关不明显,说明提高产量的首要条件是增加结果数。但结果数过多又影响个体发育,易出现小瓜。因此,我们认为采取适当的农艺措施, In order to solve the problems of low yield, high yield and unstable yield, poor product performance and unmatched technology in watermelon production in our province, Kaifeng Agricultural Research Institute conducted high quality and high yield cultivation techniques in 1987-1991. Now watermelon high yield cultivation and production methods and the main technical indicators, such as selection of varieties summarized later. First, the rational close planting, coordinating the relationship between individuals and groups Through the Harvest on the 2nd high yield and quality of watermelon reasonable group structure, fertility law and other studies have shown that the number of results and yield was significantly positively correlated single output and weight is not obvious, that The first condition to increase production is to increase the number of results. However, too many results affect the individual development, prone to small melon. Therefore, we think that adopting appropriate agronomic measures,
