西瓜—水稻高效轮作模式集成试验

西瓜连作易造成连作障碍,导致病害加重,产量和品质下降,不利于优质栽培和效益稳定。通过合理安排茬口,将西瓜与水稻等作物轮作复种,并采用品种比较试验、不同茬口及育苗方式试验、不同施肥方式试验,探索出以早佳-8424西瓜为主栽品种的西瓜—水稻轮作栽培模式和生物有机肥配方施肥技术,667 m²产值达1万元,纯效益达6 000元,实现了缓控连作障碍,促进了西瓜优质、高产高效栽培和粮菜绿色生产。

Integrated Experiment of Watermelon-Rice High Efficiency Rotation Cultivation Mode

Abstract: Continuous cropping of watermelon is easy to cause continuous cropping obstacles, such as disease aggravation, yield and quality decline, which is not conducive to high-quality cultivation and stable benefit. Through the rational crop rotation arrangement of watermelon, rice and other crops were rotated, the tests of cultivar comparison, different stubble and seedling raising methods, and different fertilization methods were carried out. Finally, technologies of watermelon-rice rotation cultivation mode and formula fertilization of biological organic fertilizer with ''Zaojiia-8424'' as the main cultivar were summarized. The output value reached 10 000 yuan per 667 m2 and the net benefit reached 6 000 yuan per 667 m2. The continuous cropping obstacle wasrelieved, and thehigh quality, high yield and high efficiency cultivation of watermelon and green production of grain and vegetablewere promoted.
