preparation example Construction

[0034] In the present invention, when the ground temperature of 10 cm is stable above 15 DEG C, the fresh-eating sweet potato seedlings are transplanted through membrane rupture. In the present invention, the fresh-eating sweet potato varieties are preferably high-quality, high-yield, disease-resistant, and highly recognized in the market. Specifically, Jishu 26, Yanshu 25 and Common potato 32 are preferred in the northern potato region. Sushu 16, Zheshu 13 and Guangshu 87 are preferred in the middle and lower reaches of the Yangtze River, and Guangshu 87 and Pushu 32 are preferred in the southern potato regions. The selected varieties of the invention have good quality, high disease resistance, stable yield, especially high market acceptance and good prospects for popularization and application, which lay a foundation for the cultivation method provided by the invention to obtain higher economic benefits. In the present invention, the preparation method of the fresh-eating sw...

Abstract

The invention relates to a fresh-eating-type sweet potato planting method based on water and fertilizer integration, and belongs to the technical field of agricultural planting. The planting method comprises the following steps that 1) from November to December every year, deep ploughing is conducted, and in April, harrowing and land preparation are conducted; 2) integrated ridging, film mulchingand drip irrigation belt laying are conducted; 3) when the 10-centimeter ground temperature is stabilized at 15 DEG C or above, fresh-eating sweet potato seedlings are transplanted after film breaking; 4) after transplantation, water dripping, dripping of a first fertilizer mixed with water and dripping of a second fertilizer mixed with water are conducted; 5) from 50 to 70 days after transplantation, vigorous growth controlling is conducted. According to the planting method, the average per unit yield level of sweet potatoes can be greatly improved, the production cost is reduced, the sweet potato production level and market competitiveness are improved comprehensively, the income of potato farmers is increased, sustained and stable production of the sweet potatoes is achieved, and healthy development of the sweet potato industry is promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a high-yield and high-efficiency cultivation method for fresh sweet potatoes based on the integration of water and fertilizer. Background technique [0002] With the change of the consumption concept of Chinese residents, the consumption of fresh sweet potato and sweet potato processed products is increasing year by year, and the added value of processed products is high and the economic benefits are remarkable. However, in recent years, with the development and changes of agriculture and rural economy and society, many problems have appeared in the production of fresh sweet potatoes, and many contradictions have arisen. As a barren-resistant crop, fresh sweet potatoes are mostly planted in areas with poor soil fertility and poor nutrients For marginal lands such as thin hills and dry plains, for a long time, due to unreasonable fertilization and pesticide applicati...
