Distribution of producing areas of wax gourd

Wax gourd is native to southern China and India, mainly distributed in tropical and subtropical parts of Asia, eastern Australia and Madagascar. It is an annual herb and a common vegetable. Let's take a look at the distribution of wax gourd.

Distribution of producing areas of wax gourd

Wax gourd is native to southern China and India. Wax gourd is cultivated in the north and south of China. It is one of the important vegetable varieties in summer and autumn. It plays an important role in regulating the off-season of vegetables. It is suitable for marketing, northward transportation and export. It is cultivated all over our country, and the fruits are picked when the fruits are ripe in late summer and early autumn.

The producing environment of wax gourd

1. Temperature: wax gourd is a temperature-loving and heat-resistant vegetable, which grows well under higher temperature. The optimum temperature for seed germination is about 30 ℃, the germination is slow below 20 ℃, and the seedlings can endure slightly lower temperature. The growth is slow at about 15 ℃, and it is easy to freeze when the temperature is below 10 ℃ or the temperature is about 10 ℃ for a long time, weak light and high humidity. In order to grow well at 20-25 ℃. The high temperature above 25 ℃ grows rapidly, but it is slim and easy to infect the disease. The suitable conditions for vine leaf growth, flowering and fruiting are about 25 ℃.

2. Rizhao: wax gourd is a short-day plant, but most varieties are not strict with sunshine. The seedling stage could promote the development of female and male flowers at lower temperature and short sunshine, and the occurrence of female and male flowers was earlier.

3. Moisture: wax gourd has developed root system and strong ability to absorb soil water, but it has luxuriant leaves, large transpiration area, large fruit and high water consumption, so it is not resistant to drought. With the growth and development of wax gourd, the need for water increases gradually. in the flowering and fruiting stage, vine leaves grow rapidly, especially after fruit setting, the fruit develops continuously, which needs the most water and higher air humidity. conditions such as higher air temperature and humidity are beneficial to fruit setting, but poor fruit setting occurs when the air is dry, the temperature is low or the rainfall is long. In the later stage of fruit development, especially before harvest, it is not appropriate to have too much water, otherwise, the quality will be reduced and the storage will not be tolerated.

4. Soil: soil nutrients are very important for the growth and development of wax gourd. According to research, for every 5000 kg wax gourd, about 15 kilograms of nitrogen, 12 kilograms of phosphorus and 15 kilograms of potassium are needed. The amount of absorption was less in the seedling stage and not much in the vine stage, but in the flowering and fruiting stage, especially in the early and middle stages of fruit development, and decreased in the later stage. Wax gourd has a long growth period and strong root absorption capacity, which can make good use of soil nutrients.

Selection method of wax gourd

1. The outer skin of wax gourd: the outer skin of wax gourd is very thin, so it is easy to leave scratches. When we choose, we mainly look for deep marks. The surface is smooth and there are no potholes.

2. The color of wax gourd: most wax gourds are dark green, so we can choose more dark green ones.

3, the size of wax gourd: generally very large wax gourd, cut into slices to sell, people choose according to the amount of food of their own family, choose about 1 piece on it.

4, wax gourd soft and hard: cut wax gourd slices, you can gently touch with your fingers, if you feel very soft, then it is estimated to be a little longer, choose a little harder.

5. Weight of wax gourd: when choosing, you can compare two slices. Which piece is heavy and slightly hard is good.
