近两年我市市郊莲藕生产发展很快。1982年种植面积达3,050亩,全市有40％的莲藕面积亩产达4,000斤左右。主要高产技术经验,有以下几点。 1.水层适宜 莲藕是水下泥生蔬菜,一生都需要处于适宜的水层之。下一旦断水干夹了泥,就走茎困难,着藕推迟,膨大受阻,肥料再多产量也不会高。实践证明:藕田整平后保持1—2寸深的水栽藕,有利于提高泥温和藕芽生长。以后随着温度增高和藕株长大再逐渐加深水层,一般应保持5—8寸深。至生长盛期宜加深到1尺左右。暴雨季节如积水过深,要及时排水,防止水深淹顶而使浮叶和走茎烂死。
In recent years, the city’s suburbs lotus root production has developed rapidly. In 1982, the planting area reached 3,050 mu, and 40% of the lotus root area in the whole city reached 4,000 kg per mu. The main high-yielding technical experience, the following points. 1. Water layer is suitable for underground lotus root mud vegetables, life needs in the appropriate water layer. Under the dry water once dry the mud, it is difficult to go stems, the lotus root postponed, swelling blocked, fertilizers and more yield will not be high. Practice has proved that: lotus root level to maintain 1-2 inches deep hydroponic lotus root, is conducive to raising the mud temperature and the growth of lotus root. Later as the temperature increases and the lotus grow up and then gradually deepen the aquifer, the general should maintain 5-8 inches deep. To the peak growth should deepen to about 1 foot. Rainy season, such as stagnant water, drainage should be promptly to prevent the flooding of deep flooding leaves and stems rotten.
