Fertilization techniques for High yield of Pumpkin

Pumpkin is one of our common vegetables, and it is also a favorite food for many people. Its fruit can be used as a delicacy or as a substitute for food, and the whole plant can be used medicinally. At present, it is cultivated all over the world, and many farmers always have a low yield when planting. In fact, this has something to do with the fertilization of pumpkins. Let's take a look at the high-yield fertilization techniques of pumpkins.

1. Characteristics of fertilizer requirement

Pumpkin is a vine crop, its root system is developed, deep into the soil, has a very strong water absorption and fertilizer absorption, so it has a strong tolerance to drought and poverty. Therefore, when planting, the soil requirements are not strict, but it is suitable to be planted in the sandy loam with deep soil layer, good drainage and fast heating up. Pumpkin has less demand for fertility at seedling stage, but when the fruit is enlarged, the demand for fertility increases sharply, especially nitrogen fertilizer, followed by potassium, phosphorus absorption increases watering. However, in the early stage of growth, if there is too much nitrogen fertilizer, it is easy to cause the stems and leaves to grow and fall melons easily.

2. Base fertilizer

Base fertilizer is mainly organic fertilizer, with nitrogen, phosphorus and potassium fertilizer, commonly used are barnyard manure, compost or farm manure, the amount of base fertilizer is relatively large, accounting for about half of the total fertilizer application, generally applying 3000-4000 kg of organic fertilizer per mu. The nitrogen, phosphorus and potassium fertilizer was mixed with organic fertilizer and applied into the soil layer, and if the organic fertilizer was insufficient, 15-20 kg of nitrogen, phosphorus and potassium compound fertilizer was applied per mu. The application of base fertilizer generally has the methods of spreading and trenching, which is mainly to spread the fertilizer evenly on the soil and mix with the soil during soil preparation.

3. Topdressing

Topdressing is generally based on available nitrogen fertilizer, reasonable collocation of phosphorus and potassium fertilizer, topdressing should be carried out according to different growth periods of pumpkin. Nitrogen fertilizer is the main topdressing at seedling stage, and urea 5-8 per mu is generally applied to promote seedling growth. During the fruit period, not only sufficient nitrogen fertilizer should be supplied, but also phosphorus and potassium fertilizer should be added in time to promote fruit expansion. Generally, 10-15 kg of urea and 5-10 kg of potassium sulfate should be applied per mu twice in the whole fruit period.

4. Foliar fertilizer spraying

In the middle and later stage of pumpkin growth, the absorption capacity of root system is weak, in order to ensure the growth and development of pumpkin and avoid premature senescence, it is necessary to use the method of external fertilization to supplement nutrients to the plant, and the most commonly used is foliar fertilizer spraying. Urea, chloride fertilizer and potassium dihydrogen phosphate are generally used to make a very low concentration of mixed solution, which is sprayed every 7-10 days for 2-3 times.
