How to Fertilize Winter Melon? A Detailed Guide to the Latest Methods
Winter melon is an annual plant of the Cucurbitaceae family, cultivated throughout our country, with wild winter melon still found in some areas. Winter melon is a common vegetable on our dining tables, and it can also be processed into candy, namely the traditional Chinese delicacy winter melon candy; in addition, both the seeds and the peel of winter melon can be used as medicine, having a swelling-reducing and diuretic effect. So how should winter melon be fertilized during cultivation? Let us learn its fertilization methods together below.
1. Characteristics of Winter Melon's Fertilizer Needs
The root system of winter melon is relatively well developed and its growth is relatively vigorous, but its nutrient requirements differ at each growth stage, so we need to fertilize according to the characteristics of winter melon's fertilizer needs. Winter melon's yield is generally relatively high and its fertilizer requirement is also relatively large; winter melon's nutrient needs are mainly potassium fertilizer, followed by nitrogen fertilizer, and then phosphorus fertilizer. Of course, we also need to implement specific fertilization techniques according to the local planting climate, soil conditions and various other aspects.
2. Principles of Fertilization
The principles of fertilizing winter melon are actually quite simple, similar to those for general crops. Usually the basis is heavy application of base fertilizer, with the principle of frequent application of thin fertilizer, and then according to winter melon's different growth stages such as the seedling stage, growth stage, flowering stage and fruit-fattening stage, fertilization is carried out reasonably, including comprehensive evaluation of all aspects such as the choice of fertilizer type, nutrient concentration and fertilization amount, and then the best fertilization plan is made.
3. Fertilization Techniques
Winter melon fertilization techniques mainly include two aspects, namely base fertilizer and topdressing. Base fertilizer is generally applied when planting winter melon, and according to the characteristics of winter melon's fertilizer needs, base fertilizer is applied heavily, mainly decomposed barnyard manure, combined with the use of phosphorus and potassium fertilizers. The later topdressing then needs to be divided into growth-stage topdressing, flowering-stage topdressing, fruit-fattening-stage topdressing and late-stage topdressing. The growth stage mainly uses nitrogen fertilizer; the flowering stage and fruit-fattening stage mainly use phosphorus and potassium fertilizers, and during the fruit-fattening stage foliar fertilizer also needs to be used in combination; in the late growth stage, in order to prevent the winter melon vines from aging, nitrogen fertilizer needs to be reasonably applied as topdressing to supplement the nutrients needed by the vines, so as to increase winter melon's yield.
4. Precautions for Fertilization
Fertilizing winter melon is actually fairly simple, but when fertilizing we still need to pay attention to these two points. The first point is not to apply nitrogen fertilizer in a one-sided way, so as to avoid excessive vegetative growth of branches and leaves, which would not only increase planting costs but also trigger a series of pests and diseases, while also reducing winter melon's yield. The second point is that fertilization should be carried out according to weather conditions; generally it is best to choose a sunny or cloudy day, and never carry it out on rainy days or before and after rain.
The above are the winter melon fertilization methods compiled and summarized by the editor, hoping to help everyone grow winter melon better. If you want to learn more information, you can follow us; more and even more wonderful agricultural planting knowledge is waiting for you.
