What kind of fertilizer is used for planting cantaloupes

Cantaloupe needs a large amount of fertilizer, such as nitrogen, phosphorus, potassium, calcium and boron, in the process of planting, the collocation and quantity of chemical fertilizer should be adjusted according to different growth stages, plant growth and planting purpose of cantaloupe. Spraying compound fertilizer or special chemical fertilizer can improve the yield and quality of cantaloupe to a certain extent, and chlorine-containing fertilizers should not be used when planting muskmelon. So as not to affect the growth of cantaloupe.

What kind of fertilizer is used to grow cantaloupe

Cantaloupe needs a large amount of fertilizer, not only nitrogen, phosphorus, potassium and other fertilizers, but also sufficient trace elements such as calcium and boron. They like nitrate nitrogen and can be applied when planting. We should pay attention to the cultivation of cantaloupe is not allowed to apply chlorine-containing fertilizer.

The demand for fertilizer of cantaloupe is less in the seedling stage, and the demand for nitrogen, phosphorus and potassium will increase gradually after flowering. Generally, the absorption of nitrogen and potassium will reach the highest in about 16-17 days after fruit setting, and the absorption of phosphorus and calcium will reach the highest after 26-27 days.

Adequate calcium and boron will increase the sweetness and appearance of the fruit. If there is not enough calcium, the surface of the melon fruit will be rough and white, and if the boron is not enough, the flesh of the melon will appear brown spots.

Matters needing attention in fertilization of cantaloupe

In order to ensure the adequate supply of nitrogen, phosphorus and potassium during the growth period of muskmelon, the absorption ratio of nitrogen, phosphorus and potassium is 21.7kg and 3.7, that is, for every cantaloupe to produce 1000kg, it needs 2.5-3.5kg nitrogen, 1.3-1.7kg phosphorus and 4.4-6.8kg potassium.

1. Base fertilizer application: cantaloupe is planted mainly with rotten farm manure, but also with nitrogen, phosphorus and potassium fertilizer. the general application ratio is 2500-3000kg/ mu mature farm manure, 5-6kg/ mu urea, 10-15kg/ mu potassium sulfate, 10-15kh/ mu diammonium, or 25-30kg/ mu potato compound fertilizer.

2. Topdressing: muskmelon does not need nutrients in different growth periods. The frequency and amount of topdressing are mainly based on the situation of melon seedlings, generally only 1-2 times are needed, the first time is after 5-6 true leaves are coring, mainly nitrogen fertilizer, phosphate fertilizer and potash fertilizer are needed, and 5-10kg urea is applied per mu. The second time was 10-15 days after flowering, mainly applied nitrogen and potassium fertilizer, supplemented with 3-5kg urea and 5-10kg potassium sulfate. If too much nitrogen fertilizer is applied, it will cause the excessive growth of cantaloupe plants, suppress flower bud differentiation, and lead to the phenomenon of falling flowers and fruits, so the quantity of topdressing urea should be determined according to the growth of muskmelon.

3. Extra-root topdressing: when muskmelon is fruited, 0.3% urea + 0.2% potassium dihydrogen phosphate mixture is sprayed to the page every other week, and it can also be sprayed with Suele boron, which can improve the fruit setting rate of cantaloupe and increase the sweetness of the fruit.

Reasonable application of chemical fertilizer can improve the yield and fruit quality, but if the chemical fertilizer is not used properly, it will reduce the fruit quality, especially in the planting process, especially in the planting land with low content of organic matter and poor performance of water and fertilizer conservation. It must be used in conjunction with organic fertilizer in order to play a better role.

When spreading, it is necessary to ensure that nitrogen, phosphorus and potassium fertilizers are properly matched, and not only nitrogen fertilizer is applied alone.

Different growth periods, plant growth and different planting purposes of muskmelon determine the type and quantity of chemical fertilizer applied. In order to promote the development of their root system, nitrogen and phosphorus fertilizer are mainly applied in the seedling stage, and nitrogen fertilizer is mainly applied in the vine extension stage to make the stems and leaves grow healthily. In order to improve the fruit quality, potassium fertilizer and nitrogen fertilizer are mainly applied.

When planting cantaloupe, applying compound or special chemical fertilizer can improve the yield and quality of cantaloupe.
