传统的红薯育苗技术是将秋季收获的红薯通过储藏,在春季栽植培育薯藤。再将薯藤剪截成藤段扦插繁育成红薯苗。这种方法费工、费时、费种薯,冬季的储藏技术不易掌握,影响翌年繁殖。现给大家介绍三种红薯育苗新方法:一、薯藤冬眠育苗法薯藤冬眠育苗法是将秋天收获的薯藤留至第2年作红薯苗。1、剪藤:在秋季红薯收获后,选择无霜冻、无病害的健壮薯藤,去除叶片,保留1厘米叶柄,按每两节一段剪截。2、强制休眠:将剪好的薯藤放入浓
The traditional sweet potato seedling technology is to harvest the sweet potato harvest in the fall, planting and cultivating potato vine in the spring. Then cut the rattan cut into rattan cuttings into sweet potato seedlings. This method of labor, time-consuming, cost of seed, winter storage technology is not easy to grasp, affecting the breeding next year. Now we introduce three new methods of sweet potato nursery: First, the potato vine hibernation nursery method potato vine hibernation nursery method is the autumn harvest of potato vine to the second year as a sweet potato seedlings. 1, cut the rattan: sweet potato harvest in the fall, choose no frost, disease-free robust potato vine, remove the leaves, leaving 1 cm petiole, cut into sections per two sections. 2, forced dormancy: the cut potato put into thick vine
