长沙地区早春苦瓜播期及栽培模式比较试验

Comparison of Sowing Date and Cultivation Model of Early Spring Balsam Pear in Changsha Area

以兴蔬春华苦瓜为材料,在长沙地区分别进行4种不同播期、栽培模式的比较试验,探讨不同播期及栽培模式对长沙地区早春苦瓜产量及经济效益的影响。试验结果表明,在长沙地区,2月底播种,采用地膜覆盖加小拱棚的栽培模式(即A2B2模式),能获得最大的经济效益,是早春苦瓜高产、高效、无公害栽培的最佳方式。

Using Balsam pear as experimental materials, the four different comparative experiments were separately compared in Changsha area in order to discuss the effects of different sowing dates and cultivation models on the yield and economic benefit. The results indicated that the best way of high yield, high efficiency and pollution-free cultivation in early spring balsam pear in Changsha area is as follow： the most suitable sowing period was end of Feb. and the optimal cultivated model was to use small vault cover as well as film mulching namely A2B2 to obtain the maximum economic bene-fits.
