Embodiment 1

[0039] A planting method of selenium-enriched dry lotus root, comprising the following steps:

[0040] a. Select a field with deep soil layer, loose and fertile soil as a planting field, and establish a drainage and irrigation system;

[0041] b. Three months before the planting of dry lotus root, plow the planting field 40 cm deep, apply soil disinfectant, and after 5 days of soil disinfection, apply a mixture of selenium ore powder and metallurgical slag powder in the mass ratio of 1:1 to the planting field The resulting mineral powder is 80kg / mu. After sterilizing the soil for 10 days, apply calcium magnesium potassium soil conditioner or calcium potassium soil conditioner 20kg / mu to the planting field, and then deeply plow 40 cm. After applying 1200kg / mu of selenium-rich base fertilizer, plow 40cm deep;

Abstract

The invention discloses a plantation method of selenium-rich edible canna. The method comprises the following steps: establishing a water irrigation and drainage system; applying mineral powder and a selenium-rich base fertilizer; carrying out breeding edible canna cutting and breeding; spreading fine sands and wood chips before sowing; digging plantation pits, and planting the breeding edible canna; and sprinkling a selenium-rich nutrient solution when the height of edible canna seedlings reaches 10-15 cm, and applying a selenium-rich fertilizer after the edible canna seedlings are germinated for 30-35 d. Scientific cultivation management is carried out, the selenium mineral powder and the selenium-rich base fertilizer are applied to the plantation field in the soil preparation process, and the selenium-rich nutrient solution and the selenium-rich fertilizer are applied in the plantation process, so harvested edible canna stem tubers have high output, are rich in the selenium element, and have extremely high nutrition values and economic values.

Description

technical field [0001] The invention relates to the field of crop planting. More specifically, the present invention relates to a method for planting selenium-enriched dry lotus root. Background technique [0002] Dry lotus root, also known as plantain taro, edible canna, etc., is a plant of the genus Canna in the banana family. It is native to South America and other places, and was introduced into my country for cultivation in the middle of the last century. Dry lotus root has become a new raw material source of high-value starch in Asia. Dry root starch has large particle size, low gelatinization temperature, good paste transparency, high chain starch content, good film-forming property, and its molecular weight is also large. It is similar to potato Starch is close and has good application properties. The development and utilization of dry lotus root is mainly to produce starch, and to develop starch deep-processing products and food items such as vermicelli and vermic...
