Novel planting method capable of saving cost and enhancing effectiveness for lotus roots

Abstract

The invention aims at providing a novel planting method capable of saving the cost and enhancing effectiveness for lotus roots. The method includes the following steps of selecting good small lotus roots, culturing robust seedlings, selecting a seedling raising field, conducting field preparation, transplanting the seedlings, conducting field management, conducting topdressing separately, conducting weeding, removing leaves, removing flowers, rotating the heads of the lotus roots, conducting prevention and control of diseases and pest disasters, and conducting prevention and control of aphids.After spade leaves of the lotus roots grow out, the back sides of the spade leaves are light red; when the margins of vertical leaves of base parts start to become withered and yellow, the lotus roots are matured enough, and harvesting can be conducted. Compared with the prior art, the method has the advantages that the cost of the lotus roots is extremely low and almost equal to zero; the smalllotus roots are adopted as seeds, the labor intensity is low, the hired manpower basically belongs to women, and the expense for the manpower is small; labor for intensive cutting of the lotus roots is avoided; through dense planting, the yield per mu is increased by 200 kg or above; the stalks of the lotus roots planted by means of the method are smaller than those of conventionally planted lotusroots, and the quality of the lotus roots planted by means of the method is high.

Description

technical field [0001] The invention belongs to the technical field of lotus root planting, and in particular relates to a lotus root planting method. Background technique [0002] Lotus root (Nelumbo nucifera Gaertn) is a perennial aquatic herbaceous plant of Nymphaeaceae. It is one of the characteristic aquatic vegetables widely cultivated in China and one of the important foreign exchange earning vegetables for export. [0003] Lotus root is the aquatic vegetable with the largest cultivation area in China. It is suitable for planting in paddy fields, ponds, and lakes. It is mainly distributed in the three major river basins of the Yangtze River, Pearl River, and Yellow River. Mainly in the province, the production of lotus root is the most widely planted, and the national planting area is 200,000 hm 2 above. Its products are high-carbohydrate and low-fat foods, except for protein (0.94-2.4%), starch (8.4-22.7%), vitamin C (2.59-35.0mg·100g -1 ), vitamin B 2 , Vitamin ...

AI Technical Summary

Problems solved by technology

Disadvantages: First, the amount of seeds used is large, and the cost of lotus root seeds is high; second, the time for planting lotus roots is concentrated, which leads to an increase in labor prices. The daily wages of male laborers are 200 yuan and female laborers are 80 yuan a day. The labor intensity is relatively high, and most of the male labor forces are employed, so the labor cost is high; the third is that the commercial lotus root reserved as lotus root seed cannot be sold, which reduces the relative output of commercial lotus root and reduces income.
