What are the melon fertilization techniques(12cm plastic grow pots)? For many farmers who grow melons, understanding these issues can enhance melon growth and achieve better economic income. The following small series will lead everyone to understand the fertilizer and fertilization technology required for melon: Melon needs a large amount of fertilizer(3.5 inch square plastic pots), not only requires a large number of elements such as nitrogen, phosphorus, potassium, but also sensitive to trace elements such as calcium and boron.(15 gallon plastic nursery plant pots for sale)
Therefore, the ratio of nitrogen, phosphorus and potassium absorption is 2:1:3.7(plastic terracotta pots wholesale). The minimum amount of fertilizer is needed during seedling stage, and the absorption of nitrogen, phosphorus and potassium is gradually increased after flowering. The peak of nitrogen and potassium absorption is 16-17 days after fruit setting, and the peak of phosphorus and calcium absorption is 26-27 days after fruit setting(small nursery pots). Calcium and boron not only affect the sweetness of the fruit, but also affect the appearance of the fruit.
The application of urea should determine the specific amount of fertilizer according to the growth of melon(110mm plastic grow pots). Mainly based on base fertilizer, base fertilizer is mainly used with decomposed farmyard manure, combined with application of nitrogen, phosphorus and potassium fertilizer. Generally, 2500-3000 kg of decomposed farmyard manure(plastic seedling pots), 5-6 kg of urea, 10-15 kg of diammonium and 10-15 kg of potassium sulfate are applied per mu. , or potato compound fertilizer 25-30kg.
(15 gallon plastic nursery plant pots for sale)For every 1000kg of melon produced, it needs to absorb 2.5-3.5kg of nitrogen, 1.3-1.7kg of phosphorus and 4.4-6.8kg of potassium(11cm plastic grow pots). Melon is similar to nitrate nitrogen, and it is advisable to apply nitrate nitrogen fertilizer. The calcium is insufficient, the surface of the fruit is rough and white, and the flesh is prone to brown spots when boron is absent. Melon is a chlorine-free crop and it is not advisable to apply chlorine-containing fertilizer(1 gallon plastic pots). It is imperative to apply a single nitrogen fertilizer.
According to the different needs of nutrients in different growth stages of melon(100mm plastic grow pots), the seedlings should be properly topdressed. Improve the yield, generally chasing 1-2 times, after topping, topdressing, with phosphorus, potassium fertilizer, mu 5-10 kg of urea, the second top dressing 10-15 days after flowering, mainly nitrogen and potassium, urea 3 - 5kg, potassium sulfate 5-10kg(large nursery pots). Excessive application of nitrogen fertilizer can easily cause melon plants to grow long, inhibit flower bud differentiation, and cause falling flowers and fruits.
(15 gallon plastic nursery plant pots for sale)Practice has proved that foliar fertilizer is sprayed every 7 days after fruit setting, usually 2-3 times(10.5cm plastic grow pots). It can be sprayed with a mixture of 0.3% urea + 0.2% potassium dihydrogen phosphate. Generally, it can also be combined with the application of Suile boron, which can increase the fruit setting rate and increase the sweetness of the fruit(round plastic plant pots). Reasonable use of chemical fertilizers can have a good effect of increasing production and quality, and if used improperly, it will lead to a decline in quality.
What kind of fertilizer is used for melon(10cm plastic grow pots)? Moreover, we must pay attention to the following principles: it must be combined with organic fertilizers to play a better role, especially in the areas with low organic matter and poor water retention. Attention must be paid to the reasonable combination of the three elements of nitrogen, phosphorus and potassium(large plastic plant pots uk). The type and amount of chemical fertilizer applied should be determined according to different growth stages, plant growth and different cultivation purposes.
