象山县地处浙江东部沿海,海洋性气候特点明显。在常年西瓜栽培中多受“梅雨”、“台风”影响,瓜农生产风险较大。近年来,开展西瓜简易棚栽植技术的应用研究,取得了可喜的成效。 1.棚栽西瓜的效益棚栽西瓜表现产量高而稳,瓜果糖度高,上市季节早,经济效益佳。据调查统计,2000年全县棚栽西瓜面积600亩(1亩=667平方米,下同),2月初播种,5
Xiangshan County is located in the eastern coast of Zhejiang Province, obvious maritime climate. Perennial watermelon cultivation in the “Meiyu”, “Typhoon” impact, melon farmers produce a greater risk. In recent years, the application of watermelon simple shed planting technology has been achieved, and achieved gratifying results. 1. shed planting watermelon benefits shed planting watermelon performance high yield and stability, high sugar content of fruits and vegetables, early market season, good economic returns. According to the survey statistics, in 2000 the county planted watermelon area of 600 acres (1 mu = 667 square meters, the same below), sowing in early February, 5
