为提高南瓜制种单位面积的收入,结合当地生产实际情况,经笔者3年技术攻关和制种户生产实践,研究出一套适合湘北地区推广的早熟南瓜与油菜、棉花间套作制种的栽培技术。采用此栽培模式产生的效益每667 m2达6 600.3元,经济效益可观。1品种与种植模式试验地点设在湘北某旱作地,前作为苎麻、棉花。试验南瓜为早熟、高产南瓜P423组合。油菜品种为中早熟、丰产抗病、油质好的双低油菜品种油研7号;棉花品种为产量高、桃子大、品质好、抗逆性强的抗虫杂交棉品种中棉所63[1]。采用油菜—南瓜—棉花间套作制种栽培模式南瓜制种地每畦的中央栽5行油菜,油菜定植时畦的两边预留栽南瓜苗的垄,垄宽55 cm。油菜结荚
In order to improve the per unit area of pumpkin seed production income, combined with the actual production of local conditions, the author three years of technical research and production system seed production practice, developed a set of suitable for the promotion of Xiangbei region of precocious pumpkin and rapeseed, cotton interplanting Cultivation Techniques. The benefits of using this cultivation mode are 6 600.3 yuan for every 667 m2, with considerable economic benefits. A variety of varieties and planting mode Test sites located in a dry land in northern Hunan, before as ramie, cotton. Test pumpkin is a precocious, high-yield pumpkin P423 combination. Rape varieties are middle-early-maturing, high-yielding disease-resistant, good oil quality double-low rapeseed oil Yan 7; cotton varieties are high yield, peach, good quality, 1]. Using rapeseed - pumpkin - cotton intercropping cultivation mode Pumpkin planted in the central planting five rows of rape, Rape planted on both sides of the reserved pumpkin planting ridge, ridge width 55 cm. Rape pods
