Cucumber grows fast, has many results and is hi-fertilized. However, its root system is shallow, fertilizer absorption and fertility are weak. Nitrate-like nitrogen fertilizer, especially soil solution containing high-level ammonium nitrogen, cannot be tolerated. Therefore, the type and quantity of fertilizer are more stringent. . According to the research, every 1000 pounds of cucumber produced needs to absorb 1.9 to 2.7 kg of nitrogen (N), 0.8 to 0.9 kg of phosphorus (P2O5), and 3.5 to 4.0 kg of potassium (K2O). The absorption ratio of nitrogen, phosphorus, and potassium is approximately It is 1:0.5:1.5.
The melon has good resistance to fertility, high yield, and needs more fertilizer. In particular, the requirement of phosphate fertilizer is more than that of ordinary vegetables, and the requirement of potassium fertilizer is relatively small. According to the measurement, every production of 1000 pounds of wax gourd requires about 1.0-3.6 kg of nitrogen (N), 0.6-1.5 kg of phosphorus (P2O5), 1.5-3.0 kg of potassium (K2O), and the absorption ratio of nitrogen, phosphorus, and potassium is about 1: 0.5:1.1.
Zucchini requires a large amount of fertilizer. Each production of 1000 pounds of zucchini requires approximately 3.9 to 5.5 kg of nitrogen (N), 2.1 to 2.3 kg of phosphorus (P2O5), and 4 to 7.3 kg of potassium (K2O). The absorption ratio of nitrogen, phosphorus, and potassium is approximately 1:0.3:1.5. .
Bitter gourd is fat and impatient. Bitter gourd is a high-nitrogen type vegetable, and about 5.3 kg of nitrogen (N), 1.7 kg of phosphorus (P2O5), and 6.7 kg of potassium (K2O) are needed to produce 1,000 kg of bitter gourd. The absorption ratio of nitrogen, phosphorus, and potassium is about 1: 0.5:1.2.
The roots of pumpkins are well-developed and require less seedlings during the seedling period. It is the time when the largest amount of fertilizer is needed to enter the fruit enlargement period. Each production of 1000 pounds of pumpkin about to absorb nitrogen (N) 3.5 ~ 5.5 kg, phosphorus (P2O5) 1.5 ~ 2.2 kg, potassium (K2O) 5.3 ~ 7.3 kg, nitrogen, phosphorus, potassium absorption ratio of about 1:0.4: 1.5.
West melon needs a large amount of fat. Nitrate-like nitrogen fertilizer, if the ammonium nitrogen fertilizer content is too high, it will affect the photosynthetic efficiency of melon, and it will cause ammonium poisoning. Calcium and boron have a certain effect on the appearance and sugar accumulation of melon fruit.
