Melon needs a large amount of fertilizer, nitrogen, phosphorus, potassium and calcium, boron and other fertilizers. In the planting process, the mix and quantity of fertilizer should be based on the different growth stages of the melon, the growth of the plant and the purpose of planting. Adjustment, application of compound fertilizer or special fertilizer can improve the yield and quality of melon to a certain extent. When planting cantaloupe, avoid using chlorine-containing fertilizer to avoid affecting the growth of melon.
What fertilizer is used to grow melon?
Melon needs a large amount of fertilizer, not only needs to apply nitrogen, phosphorus, potassium and other fertilizers, but also needs calcium, boron and other trace elements. They like nitrate nitrogen. When planting, they can apply nitrate nitrogen fertilizer. Pay attention to planting cantaloupe. It is not possible to apply chlorine-containing fertilizers.
Melon has less demand for fertilizer during seedling stage. After flowering, the demand for nitrogen, phosphorus and potassium will gradually increase. Generally, the absorption of nitrogen and potassium will reach about 16-17 days after fruit setting. The highest, after 26-27 days of fruit set, the highest absorption of phosphorus and calcium.
Adequate calcium and boron will increase the sweetness of the fruit and make it look beautiful. If the calcium is not enough, the surface of the melon fruit will be rough and white. If the boron is not enough, the melon will have brown spots.
Melon fertilizer fertilization considerations
In the growth period of melon, ensure that the supply of nitrogen, phosphorus and potassium is sufficient. Their absorption ratio of nitrogen, phosphorus and potassium is 2:1:3.7, that is, 2.5-3.5kg of nitrogen is needed for every 1000kg of cantaloupe produced. - 1.7 kg of phosphorus, 4.4-6.8 kg of potassium.
1. Base fertilizer application: planting cantaloupe, mainly applying decomposed farmyard manure, but also cooperating with nitrogen, phosphorus and potassium fertilizers. The general application rate is 2500-3000kg/mu decomposed farmyard manure, 5-6kg/mu urea, 10 -15kg/mu potassium sulfate, 10-15kh/mu diammonium, or 25-30kg/mu potato compound fertilizer.
2, topdressing: the demand for nutrients in different growth stages of cantaloupe is not used, the number and amount of top dressing mainly depends on the situation of melon seedlings, generally only need to chase 1-2 times of fertilizer, the first time is 5-6 pieces After the true leaves are topped, the main application of nitrogen fertilizer, combined with phosphate fertilizer and potassium fertilizer, 5-10 kg of urea per acre; the second is after 10-15 days of flowering, mainly applying nitrogen and potassium fertilizer, supplemented by 3- 5 kg of urea and 5-10 kg of potassium sulfate. If too much nitrogen is applied, it will cause the melon plants to grow long, suppress the flower bud differentiation, and the phenomenon of falling flowers and fruit. Therefore, the amount of urea should be determined according to the growth of the melon.
3, the top of the top dressing: When the melon is fruit, spray a 0.3% urea + 0.2% potassium dihydrogen phosphate mixture every other week, and also spray with the speed of boron, can improve the fruiting rate of cantaloupe The sweetness of the fruit will also increase.
Reasonable application of chemical fertilizers can increase yield and fruit quality. However, if the fertilizer is used improperly, the quality of the fruit will be reduced. In the process of planting, especially when the fertilizer is poorly applied to the planting land, the fertilizer is applied. It must be used in conjunction with organic fertilizers in order to play a better role.
When applying, ensure that the nitrogen, phosphorus and potassium fertilizers are properly matched. It is not allowed to apply nitrogen fertilizer alone.
The different growth stages of cantaloupe, the growth of plants and the different planting purposes determine the type and quantity of fertilizer. In the seedling stage, they promote the development of their roots, mainly applying nitrogen and phosphate fertilizers. It is able to grow healthily, mainly applying nitrogen fertilizer. In order to improve the quality of the fruit when planting the melon, the main application is potassium fertilizer and nitrogen fertilizer.
When planting cantaloupe, applying a compound or special fertilizer can increase the yield and quality of cantaloupe. (get rich)
