A nutrient management method for simultaneously increasing the content of propanol in wax gourd fruit and improving the fruit shape of wax gourd

Abstract

The invention provides a nutrient management method for simultaneously increasing the content of propanol in wax gourd fruit and improving the shape of wax gourd fruit, comprising applying fertilizers containing nitrogen, phosphorus pentoxide, potassium oxide, magnesium oxide and calcium oxide to wax gourd plants. The inventor found through experiments that the nutrient management method containing nitrogen, phosphorus pentoxide, potassium oxide, magnesium oxide and calcium oxide provides substances and materials for the expansion of pulp cells and the formation of fruit yield and quality of wax gourd in the fruit expansion stage by promoting the transportation of carbohydrates. Metabolic basis, thus affecting the metabolism of pyruvate on the one hand, significantly increasing the content of tartronic acid in fruits, and increasing its content by nearly 10 times; Fertilizers can reduce the accumulation of carbohydrates such as starch in the leaves, significantly promote the transport of photosynthetic products in the leaves of wax gourd plants to the fruit, and increase the volume of wax gourd pulp cells by more than 20% while improving the utilization of assimilates in wax gourd plants, and increase the length of the fruit's transverse diameter The fruit shape of the wax gourd is further improved by 30%, so that the fruit of the wax gourd is elongated and cylindrical, and the commerciality of the wax gourd is enhanced.

Description

technical field [0001] The invention belongs to the field of plant nutrient management, and in particular relates to a nutrient management method for simultaneously increasing the content of glyceric acid in wax gourd fruit and improving the fruit shape of wax gourd. Background technique [0002] Wax gourd is an important medicinal and edible crop with an annual planting area of ​​5 million mu in my country, accounting for about 50% of the total acreage of wax gourd in the world. South China is an important winter melon production base in my country, and the large-scale winter melon is especially famous all over the world. It is a pillar industry of vegetables in South China and a key crop for farmers to get rid of poverty. At the same time, winter melon is also a popular vegetable for weight loss and fat reduction among consumers. Its effective fat-lowering and weight-loss substance is a kind of melon-specific organic acid-propanol diacid, which can inhibit the conversion o...
