山药与伏汤菜(夏小青菜)、雪菜(雪里蕻)及冬青菜的间套种,是笔者近年试验探索成功的又一理想的多熟立体高效复种模式。因在周年生产过程中,可最大限度地利用当地光热资源,促进生育期与有利气候同步,从而实现最佳经济效益。我县示范推广的45亩夏种田,每亩年均净产值逾1万元(山药2250公斤×4元、汤菜900公斤×0.8元、雪菜2000公斤×0.5元、冬青菜2000公斤×0.6元),经济、社会效益极为显著。其复种要点:
Yam and V soup (summer small greens), pickled cabbage (snowy) and winter intercropping, is the author in recent years to explore the success of another ideal multi-cooked three-dimensional high-efficiency multiple cropping pattern. Because in the annual production process, to maximize the use of local light and heat resources, and promote the growth of favorable climate synchronization, in order to achieve the best value for money. In our county, 45 mu of summer farmland will be popularized, and the annual average net output value per mu will be over 10,000 yuan (2250 kg x 4 yuan for yam, 900 kg x 0.8 yuan for soup, 2000 kg x 0.5 yuan for pickled vegetables and 2,000 kg for winter vegetables × 0.6 yuan ), Economic, social benefits are extremely significant. The multiplication points:
