不同播期对山区甜椒夏秋反季节栽培产量的影响

The Effect of Different Sowing Time on Yield of Sweet Red Pepper under Off-season Cultivation in the Mountainous Area

为了选择夏秋反季节甜椒的最佳播种期，进行了不同播种期试验。结果表明：在黔西北海拔1600-1700m的山区，甜椒夏秋栽培获得较高红椒产量的播种期为3月18日至4月17日，红椒产量达3808．0-4002．6kg／667m^2，产品于8-10月上市。5月后播种甜椒不能全部转红，需采收部分青椒，上市时间9下旬至11月上旬，由于后期单价上涨，仍能获得较好的经济效益。

Daguowang, a sweet red pepper variety, was tested under different sowing time to select the optimum sowing time for its high yield under off-season cultivation in Nayong county with 1600 m to 1700 m above sea level. The results showed that the yield of Daguowang variety can be up to 3808.0kg/667m^2 to 4002. 6kg/667m^2 and its sweet red peppers can go to market from August to October when the sowing time is from 18, March to 17, April, and the peppers of Daguowang variety can not be all changed red when the sowing time is after May but it still gets the better economic benefit because the market time is delayed between the last ten-day period of September and the first ten-day period of November and its pepper price rises.
