Pumpkin is very common in our lives. It can not only be eaten, but also can be used as medicine. The medicinal value is very high. There are many varieties of pumpkins, which are widely cultivated in all parts of the North and the South. Planting pumpkins, I believe many people should pay attention to their production problems, then how to achieve high yield? Here are some high-yield planting techniques for pumpkins.
1, fertilizer characteristics
The roots of pumpkin are developed, and they have strong water absorption and fertility, drought tolerance and poor tolerance. For pumpkin planting, the soil requirements are not strict. It is best to choose the sandy loam with deep soil, good drainage and fast heating. During the seedling stage of pumpkin, there is less fertility demand. During the fruit expansion period, the fertility demand rises sharply, especially nitrogen fertilizer and potassium, and the phosphorus absorption increases. If the nitrogen fertilizer is too long in the growing season, it is easy to cause problems such as long stems and leaves.
2, base fertilizer
The base fertilizer is mainly organic fertilizer, with NPK fertilizer. Commonly used are manure, compost or farmyard manure. The application of base fertilizer is relatively large, accounting for about half of the total fertilization amount. Generally, 3000-4000 kg of organic fertilizer is applied per mu. Nitrogen, phosphorus and potassium fertilizers can also be used in combination with organic fertilizers. If organic fertilizers are insufficient, they should be supplemented with NPK fertilizers and organic fertilizers.
3, top dressing
When the pumpkin is topdressed, it is mainly based on quick-acting nitrogen fertilizer, which can effectively and rationally match the potassium fertilizer. In the seedling stage, nitrogen fertilizer can be applied, which can promote the growth of seedlings and apply urea to 5-8 environment. In its fruit period, it can supply sufficient nitrogen fertilizer, and at the same time effectively supplement the phosphorus and potassium fertilizer to promote fruit expansion, apply 10-15 kg of urea and 5-10 kg of potassium sulfate, and carry out the whole fruit twice.
4, foliar spray fertilizer
In the middle and late stages of pumpkin growth, its root absorption capacity is not strong. In order to ensure the normal development of the pumpkin and avoid premature aging, we can fertilize the roots, the most common is foliar spray fertilizer. We can also add a mixture of urea, chlorinated fertilizer, potassium dihydrogen phosphate, etc., and then spray once every other week or so, and spray 2-3 times continuously.
The above is the introduction of pumpkin high-yield planting technology. Although the pumpkin needs a relatively large amount of fertilizer, we can not blindly fertilize during the planting process. It must be rationally used with fertilizers. It is necessary to avoid the use of single fertilizer for a long time and achieve scientific and effective fertilization. Foliar spray application can be carried out in the middle and late stages of growth. This will ensure that the pumpkin grows quickly and efficiently.
