Wax gourd should be stored in a cool, ventilated and dry room after picking. The storage room should be fumigated and disinfected with potassium permanganate and formalin 2 ~ 3 days before the wax gourd enters the house, and a layer of straw mat should be laid on the ground and basket frame. When entering the room, it is generally required that the direction of the melon is the same as that when growing in the field, that is, the handle of the melon originally planted on the ground should be flat, and the handle of the melon originally planted in the shed should be upright. When stored on the ground, melons should not be piled too high because of their own weight to reduce the damage caused by mutual extrusion.

Generally, winter melon should not be turned over during storage, but it should be checked frequently, and the diseased melon should be picked out immediately. The suitable storage temperature of wax gourd is 10℃ ~ 15℃, and the relative humidity is 80% ~ 85%. Wax gourd has a large water content and a lot of respiratory heat in the early stage of storage, so it is necessary to strengthen ventilation, heat dissipation and dehumidification. If the room temperature is as high as 30℃, turn on the exhaust fan or air conditioner to cool down. If there is no ventilation to cool down, you can close the window for shading at noon with strong sunshine and open the window for ventilation in the morning and evening. The air in the storeroom should be fresh, dry and cool. In this way, the storage time of wax gourd can be prolonged.

Extended data

1, temperature

Wax gourd likes heat resistance. The optimum temperature for growth and development is 25-30℃, the optimum temperature for seed germination is 28-30℃, and the lowest temperature for root growth is 12- 16℃, which are higher than other melons and vegetables. The suitable temperature for pollination and fruit setting is about 25℃, and below 20℃ is not conducive to fruit development. ?

2. sunshine

Winter melon is a short-term crop. Short sunshine and low temperature are beneficial to flower bud differentiation, but long sunshine and sufficient illumination are needed during the whole growth period. In case of long-term rainy and low temperature in fruit period, flowers will fall, melons will melt and rotten. ?

Step 3: Moisture

Wax gourd has large leaf area, strong transpiration and high water demand, but too much or too little air humidity is not conducive to pollination, fruit setting and fruit development. ?

4. Nutrition

The growth period of wax gourd is long, and the vegetative growth of plants and the growth and development of fruits need enough soil nutrients, so it is necessary to apply more fertilizers. Fertilization is mainly based on nitrogen fertilizer, and appropriate application of phosphorus and potassium fertilizer can enhance the stress resistance of plants and increase the yield of single fruit seeds. ?
