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 increasing yield of sweet potatoes induced by glyphosate. It includes the following steps: ① preparation of medicinal solution: miscible glyphosate amine salt with water to prepare the required medicinal solution; ② foliar spraying: when the sweet potato stems and leaves are vigorously growing, spray the medicinal solution prepared in step ① liquid evenly sprayed on sweet potato stems and leaves; wherein said glyphosate amine salt is glyphosate isopropylamine salt, wherein the mass concentration of glyphosate isopropylamine salt is 41%, said glyphosate amine salt and said glyphosate amine salt The volume ratio of water is 1:(700‑800). For the first time, this application uses the commonly used herbicide glyphosate as a thriving control agent to spray sweet potatoes on the leaves. The test shows that glyphosate isopropylamine salt has a thriving control effect on sweet potatoes. After treatment, the yield of sweet potatoes is significantly improved, and the soluble sugar content The starch content has also been significantly improved. It can be seen that glyphosate can not only control the excessive growth of sweet potato stems and leaves, but also promote the conduction of photosynthetic nutrients to the 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...
