2. Wax gourd is one of the important vegetable varieties in summer and autumn, which has the characteristics of temperature tolerance, high yield and storage resistance.
Second, the origin environment and temperature of wax gourd 1 (1) wax gourd grows better at a higher temperature, and the optimum temperature for seed germination is about 30℃, and the germination becomes slow at 20℃.
(2) It grows slowly at 15℃, and it is easy to be frozen at the temperature below 10℃, with weak light and high humidity.
(3) It grows well at 20-25℃, and grows rapidly above 25℃, but it is not delicate and susceptible to diseases.
2. Sunshine (1) Wax gourd is a short-lived plant, and the requirements for sunshine are not strict.
(2) The seedling stage can promote the development at a slightly lower temperature, and the occurrence nodes of female and male flowers are advanced.
3. Moisture (1) The root system of wax gourd is developed and has strong water absorption, but the leaves are large and the fruits are large, which consumes more water, so it is not very drought-tolerant.
(2) Especially in the fruit-setting period, the fruit develops continuously and needs the most water. Higher air humidity and temperature are beneficial to fruit-setting.
(3) At the late stage of fruit development, especially before harvesting, the water content should not be too much, otherwise the best quality and storage will be affected.
4. The soil (1) needs about 15- 18 kg of nitrogen, 12- 13 kg of phosphorus and 12- 15 per 5,000 kg of wax gourd.
(2) The absorption amount is the smallest in the seedling stage, and it is not too much in the vine-pulling stage. It is large in the flowering and fruiting stage, especially in the early and middle stages, and it decreases in the later stage.
(3) The growth cycle of wax gourd is relatively long, and the root system has strong absorption capacity, which can make good use of soil nutrients.
