Problems solved by technology

[0003] However, the existing sweet potato planting technology is relatively backward and lacks systematic and scientific planting methods, so that the overall quality of sweet potato is poor and the yield is low, especially the edible tubers are thin and small, which seriously affects its economic benefits.

Embodiment 1

[0019] The method that present embodiment induces sweet potato tuber root to expand may further comprise the steps:

[0020] ① Preparation of liquid medicine

[0021] 20 mL of glyphosate isopropylamine salt with a mass concentration of 41% is miscible with 14 L of water (that is, the volume ratio of the glyphosate amine salt to the water is 1:700) to prepare the required medicinal solution;

[0022] ②Foliar spraying

[0023] When the sweet potato stems and leaves are growing vigorously, every 667m 2 Spray the medicinal liquid prepared in step ① evenly on the sweet potato stems and leaves.

Embodiment 2

[0025] The method that present embodiment induces sweet potato tuber root to expand may further comprise the steps:

[0026] ① Preparation of liquid medicine

[0027] 20 mL of glyphosate isopropylamine salt with a mass concentration of 41% was miscible with 15 L of water (the volume ratio of the glyphosate amine salt to the water was 1:750) to prepare the required medicinal solution;

[0028] ②Foliar spraying

[0029] When the sweet potato stems and leaves are growing vigorously, every 667m 2 Spray the medicinal liquid prepared in step ① evenly on the sweet potato stems and leaves.

Embodiment 3

[0031] The method that present embodiment induces sweet potato tuber root to expand may further comprise the steps:

[0032] ① Preparation of liquid medicine

[0033] 20 mL of glyphosate isopropylamine salt with a mass concentration of 41% was miscible with 16 L of water (the volume ratio of the glyphosate amine salt to the water was 1:800) to prepare the required medicinal solution;

[0034] ②Foliar spraying

[0035] When the sweet potato stems and leaves are growing vigorously, every 667m 2 Spray the medicinal liquid prepared in step ① evenly on the sweet potato stems and leaves.

Abstract

The invention relates to the field of plant growth regulation and in particular discloses a method for inducing yield increase of sweet potatoes with glyphosate. The method comprises the following steps: (1) liquid medicine preparation, namely mixing glyhosate ammonium and water, and preparing needed liquid medicine; (2) foliage spray, namely uniformly spraying the liquid medicine prepared in thestep (1) onto sweet potato stems and leaves when the sweet potato stems and leaves grow vigorously, wherein the glyhosate ammonium is glyphosate isopropylamine, the mass concentration of the glyphosate isopropylamine is 41%, and a volume ratio of the glyhosate ammonium to the water is 1:(700-800). According to the method disclosed by the invention, the common herbicide glyphosate firstly serves asan excessive growth control agent so as to perform foliage spray on sweet potatoes. Tests show that the glyphosate isopropylamine has an effect of controlling excessive growth of the sweet potatoes,the yield of the treated sweet potatoes is obviously improved, and the content of soluble sugar and starch is obviously improved. Therefore, the glyphosate is capable of controlling excessive growth of the sweet potato stems and leaves and promoting nutrients of photosynthesis to be conducted to sweet potato roots.

Description

technical field [0001] The invention relates to the field of plant growth regulation, and in particular discloses a method for increasing yield of sweet potatoes induced by glyphosate. Background technique [0002] Sweet potato is also called sweet potato, red moss, sweet potato, sweet potato. The nutritional value of sweet potato is very high, and it is a healthy food with both medicine and food. Sweet potatoes are rich in potassium, β-carotene, folic acid, vitamin C and vitamin B6, and these 5 ingredients can help prevent cardiovascular disease. Sweet potato also has anti-diabetes, emphysema prevention and anti-cancer effects. Sweet potatoes are rich in starch, soluble sugar, dietary fiber, carotene, various vitamins, potassium, iron, copper, calcium, selenium and more than 10 kinds of trace elements and linoleic acid, etc., and have high nutritional value. Known as nutritionally balanced, almost perfect health food. Sweet potato is a low-fat, low-calorie food, which c...
