Abstract

The invention relates to a water-retaining agent special for sweet potatoes and a method for cultivating the sweet potatoes in a water-saving mode, and belongs to the technical field of agricultural materials and agricultural planting. The water-retaining agent special for the sweet potatoes is prepared from N,N-methylenebisacrylamide, carboxymethylcellulose, acrylic acid, acrylamide, potassium persulfate, potassium hydroxide, sodium hydroxide, humic acid, naphthylacetic acid, indolebutyric acid, thiophanate methyl, farmyard manure and deionized water. According to the water-retaining agent special for the sweet potatoes, the soil structure can be improved, soil water is retained and stored, seed potato germination is promoted, the seedling emergence amount is increased, the quality of potato seedlings is improved, the transplanting survival rate of the sweet potatoes is increased, root system growth and tuberous root expansion are promoted, the yield is increased, the quality is improved, and the water utilization rate is increased.

Description

technical field [0001] The invention relates to the technical fields of agricultural materials and agricultural planting, in particular to a special water-retaining agent for sweet potatoes and a method for water-saving cultivation of sweet potatoes. Background technique [0002] Sweet potato is an important grain, feed, industrial raw material and new energy crop in China, rich in nutrition and balanced in nutrition. With the improvement of people's living standards, sweet potato has become an important energy crop and health food. However, as a drought-tolerant crop, sweet potatoes are mostly planted in hilly and dry land with poor soil fertility and poor nutrients, and their potential production capacity cannot be fully utilized. Especially in semi-humid and arid areas, drought has become a limiting factor for further increase in sweet potato production. . The technical ways to increase the yield of sweet potato in dry land: first, select drought-resistant varieties; se...
