Problems solved by technology

However, these substances are all exogenous food additives, and there are many problems such as increased energy consumption, increased equipment demand, and food safety.
[0005] Existing methods for improving the taste of processed sweet potato starch products all require the addition of exogenous food additives. At present, there is no report on improving the starch composition and quality of sweet potato by improving the planting method, thereby improving the quality of sweet potato processed products

Embodiment 1

[0035] 1, adopt above-mentioned first method (separate planting sweet potato, do not interplant corn), carry out the sweet potato planting test of different varieties in the laboratory, the sweet potato planting density is 3500 plants / mu, and planting 150 days after field planting. During the whole planting process, 12h light treatment and 12h dark treatment are alternately carried out on the sweet potato; the light treatment is specifically: using an ordinary LED light emitting white light, and the light quantum flux density is 100 μmol / m 2 / s. The application rate of the nitrogen fertilizer is 6kg / mu (calculated by nitrogen element); the application rate of the potassium fertilizer is 10kg / mu (calculated by potassium element). The specific planting methods of each group are shown in Table 1.

Embodiment 2

[0053] 1. Adopt the above-mentioned preferred method, that is, interplant sweet potatoes and corn, and carry out planting experiments in the laboratory. The planting density of sweet potatoes is 2300 plants / mu; the sweet potato variety is No. 198 Yushu. During the whole planting process, 12h light treatment and 12h dark treatment are alternately carried out on the sweet potato; the light treatment is specifically: using an ordinary LED light emitting white light, and the light quantum flux density is 100 μmol / m 2 / s. The application rate of described nitrogen fertilizer is 10kg / mu (calculated by nitrogen element), and described nitrogen fertilizer is urea; The application rate of described potassium fertilizer is 15kg / mu (calculated by potassium element), and described potassium fertilizer is potassium sulfate; for calcium superphosphate. The base fertilizer application time is 3 days before planting.

Abstract

The invention belongs to the field of agricultural product planting and particularly relates to sweet potato with high starch quality and a planting method thereof. Specifically, the phosphorus content in sweet potato starch is controlled through a specific planting method so as to control quality of sweet potato starch and improve the quality of sweet potato products. The method herein has no need for exogenous additives for starch, so that safety and reliability are good; intracellular reaction conditions are mild; no additional energy is consumed; the cost is low; the sweet potato and the planting method thereof are convenient to popularize.

Description

technical field [0001] The invention belongs to the field of planting agricultural products, and in particular relates to a sweet potato with high starch quality and a planting method thereof. Background technique [0002] Sweet potato has a large planting area in my country, second only to rice, wheat and corn. At the same time, sweet potato is a starch crop, and its starch content is mostly 15% to 25%. The high content of starch allows sweet potatoes to be processed into a variety of starch products including vermicelli, vermicelli, jelly, etc., and the taste of such products is highly related to the quality of starch. Generally speaking, the better the starch quality, the more elastic and tasteful the resulting product. [0003] In the prior art, in order to increase the elasticity of the product, it is often necessary to add alum during the production process. Alum is hydrolyzed in water to form aluminum hydroxide, which can form a water-insoluble floc colloid under c...
