How to fertilize winter melon for high yield? Detailed explanation of high-yield fertilization techniques
Winter melon is a very common vegetable on our daily dining table, and it is grown all over China. When growing winter melon, yield is basically what most people pay special attention to. If you want winter melon to achieve high yield, then fertilization work is very important. Reasonable and suitable fertilization 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 brings you high-yield fertilization techniques for winter melon. Let's 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 fertilize, then applying sufficient base fertilizer is very critical. The base fertilizer is mainly decomposed farmyard manure, applied at about 6000 kg 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 for about 30 cm, and rake 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 ⟧7⟧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, an appropriate amount of recovery water should be poured. If too little base fertilizer was applied, then after the seedlings recover, a light fertilization can be properly applied once. The fertilizer is applied by watering with decomposed manure water at a concentration of about 20%, or urea or compound fertilizer can be applied in holes. The amount must be strictly controlled and must not be excessive.
During the seedling stage of winter melon, we need to pay attention to applying an appropriate amount of seedling fertilizer. Seedling fertilizer is generally light fertilizer applied with a small amount of water, to avoid excessive fertilizer generating too much heat and burning the seedlings. About seven days after the seedlings are transplanted, when the plants are recovering from transplanting, an appropriate amount of water for seedling recovery should be poured. If the base fertilizer was applied too little, then after the seedlings recover, a light application of fertilizer can be given as appropriate. Apply fermented manure water at a concentration of about 20% as the fertilizer, or apply urea or compound fertilizer in holes; the dosage must be strictly controlled and must not be excessive.
3. Vine fertilizer
Before winter melon begins to vine, the amount of topdressing should be kept at about 35% of all topdressing. 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 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 fertilization may not be needed. On the contrary, if fertility is too low, then when the seedlings have about 5 leaves, fertilization should be applied in furrows. Apply an appropriate amount of compound fertilizer per mu. After female flowers appear and until fruit set, fertilizer and water must be controlled well, especially nitrogen fertilizer, to avoid excessive growth of stems and leaves and the occurrence of fruit abortion.
4. Flowering and fruiting fertilizer
When fertilizing winter melon during the flowering and fruiting period, the amount should be kept at about 65% of the total topdressing. 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, while also ensuring complete nutrition. Then after the fruit is firmly set, a fruit-promoting fertilizer should be applied in time. In the middle and late stages of fruit expansion, the fertilization principle should be small amounts applied more frequently, with topdressing about every half month. About 25 kg of high-nitrogen-potassium compound fertilizer each time. Properly adjust the amount and frequency according to the previous fertilization situation of winter melon and the timing of the harvest period.
The above is a brief introduction to high-yield fertilization techniques for winter melon. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
