How to Fertilize Winter Melon for High Yield? Latest Technical Method Tutorial
Winter melon is a very common vegetable on our daily dining tables, and it is grown in various regions of our country. When growing winter melon, yield is basically what most people pay particular attention to. If you want winter melon to achieve high yield, then fertilization work is very important. Reasonable and appropriate fertilization work is the key to meeting the nutritional needs of winter melon growth. So how should winter melon be fertilized to achieve high yield? Today the editor has brought you the high-yield fertilization technique for winter melon. Let us take a look together below!
1. Base fertilizer
The growth period of winter melon is relatively long compared with other vegetables, so its demand for fertilizer is also relatively large. Therefore, sufficient base fertilizer must be applied before planting. Especially during the growth period of the young winter melon, if there is a lot of rain and it is inconvenient to apply fertilizer, then applying sufficient base fertilizer is very critical. The base fertilizer is mainly decomposed farmyard manure, applied at about 6000kg per mu. If the soil is barren, then an appropriate amount of compound fertilizer such as potassium sulfate can also be added. When preparing the land, spread it, then plow deeply about 30cm, and harrow it fine and level. In addition, winter melon also has a relatively large demand for calcium, so if the soil is too acidic, then an appropriate amount of lime should also be mixed in.
2. Seedling fertilizer
During the seedling stage of winter melon, we should pay attention to applying an appropriate amount of seedling fertilizer. Seedling fertilizer is generally mainly light fertilizer with a small amount of water, to avoid excessive fertilizer producing too much heat and burning the seedlings. About seven days after the seedlings are planted, when the plants are recovering from transplanting, an appropriate amount of water for seedling recovery should be poured. If too little base fertilizer was applied, then after the seedlings recover, a light fertilization can be applied appropriately. The fertilizer can be about 20% concentration decomposed manure water for pouring, or urea or compound fertilizer can be applied in holes. The amount must be strictly controlled and must not be excessive.
3. Vine fertilizer
Before winter melon has produced vines, its topdressing amount should be maintained at about 35% of the total topdressing amount. The main purpose of fertilization at this stage is to promote the growth of vines and leaves, but attention should also be paid to controlling the concentration and amount. Avoid excess causing dark green leaf color and short internodes. If the base fertilizer is sufficient and the plants are growing well, then no fertilization may be needed. On the contrary, if fertility is too low, then when the seedlings have about 5 leaves, ditch application should be carried out. Apply an appropriate amount of compound fertilizer per mu. After female flowers appear and until fruit set, fertilizer and water, especially nitrogen fertilizer, must be controlled well, to avoid excessive vegetative growth of stems and leaves causing fruit abortion.
4. Flowering and fruiting fertilizer
When fertilizing during the flowering and fruiting period of winter melon, the amount should be maintained at about 65% of the total topdressing amount. Fertilization during the flowering and fruiting period has a very large impact on the yield of winter melon. It should usually be carried out after fruit set, to avoid flower and fruit drop, and at the same time ensure complete nutrition. Then after the fruit is firmly set, apply a fruit-promoting fertilizer in time. In the middle and late stages of fruit enlargement, the fertilization principle should be small amounts applied more frequently, with topdressing about every half month. Each time about 25kg of high-nitrogen potassium compound fertilizer. Appropriately adjust the amount and frequency according to the early fertilization situation of winter melon and the time of the harvest period.
The above is a brief introduction to the high-yield fertilization technique for winter melon. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
