Abstract

The invention discloses a cultivating method for optimizing and screening red-core sweet potato variety. The cultivating method comprises the following steps: seedling propagation, soil preparation and field planting, field management and screening and picking of red-core sweet potato leaves. The growth conditions of red-core sweet potato leaves are as follows: warm weather conditions are suitablefor the red-core sweet potato leaves; the red-core sweet potato leaves can resist against high temperature but cannot resist against frost; the optimum growth temperature is 23-28 DEG C at daytime and 12-15 DEG C at night; the growth will be influenced if the temperature is above 35 DEG C or below 15 DEG C; the red-core sweet potato leaves are photophilous but do not have strict demand on light;the plant can grow healthy and strong under sufficient sunlight and the yield is high; through reasonable planting manner and scientific management manner in the invention, the insect attack can be effectively prevented, the yield of the red-core sweet potato leaves can be effectively promoted, so that fine variety of red-core sweet potato can be screened; according to the invention, the plantingmanner is simple, the number of planting personnel can be effectively reduced, the scientific management is realized and the production cost of enterprises can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of sweet potato planting, in particular to a breeding method for optimizing and screening sweet potato varieties. Background technique [0002] Sweet potatoes for leaves are called longevity vegetables, sweet potato leaves, and green velvet vegetables. It is a herbaceous vine of the genus Morning Glory in the family Convolvulaceae. It is native to Brazil, Peru and other places in South America. During the Wanli period of the Ming Dynasty, Chen Zhenlong, a Fujianese, introduced it from the Philippines to Guangdong, Fujian and other places for planting. Soon it was widely planted in the south and north of the country and the world, but mainly using underground tubers. In recent years, Chinese Hong Kong, Chinese Taiwan, Guangdong, Guangxi and other places eat tender stem tips and young leaves, which are praised as "vegetable queen" by Hong Kong because of their rich nutrition and delicious taste. In China's C...
