Pumpkin fertilizer characteristics

First, the roots of the fertilizer characteristics of the pumpkin root system is developed, the main root can be as deep as 2 meters, the first side of the root has more than 20, about 50 cm long, up to 140 cm, and can be divided into three or four lateral roots, Form a strong root group, the main root group is densely distributed in the 10 to 40 cm plough layer. Because the pumpkin roots are deep in soil and widely distributed, the ability to absorb fertilizer and water is also strong, and it has strong drought resistance and resistance to thinness. The soil requirements are not strict, even if grown in relatively thin plots. The cultivation of pumpkins in sticky and fertile soil is often caused by the growth of stems and leaves, and the yield is not high. Therefore, it is better to choose the sandy loam with deep soil, good drainage and fast heating for early maturity cultivation; the late-ripening varieties should be planted with loam with strong water retention and fertility, and the suitable soil is 6.5-7.5. When the soil fertility is sufficient, it should be properly planted, pruned and topped in time, and the fertility can be fully utilized to obtain high yield.

Second, the pumpkin needs fertilizer dynamics
The nutrient absorption and absorption ratio of pumpkin in different growth stages are different. In the seedling stage, the fertilizer needs to be less. When entering the fruit expansion period, it is the period with the largest amount of fertilizer. Especially, the absorption of nitrogen increases sharply, and the potassium has a similar trend, and the phosphorus absorption increases little. According to the Japanese Miyazaki study, the absorption of five elements (nitrogen, phosphorus, potassium, calcium, magnesium) in the first 1/3 of the 137 days from the colonization to the pulling of the pumpkin is slow, and the middle third is Time has grown rapidly, and growth has been most pronounced in the last 1/3 of the time. The absorption of the five elements in the whole period is the highest in potassium and nitrogen, the middle in calcium, and the least in magnesium and phosphorus. The increase in production is in line with the overall trend of absorption of the five elements, and it is also rising rapidly in the last 1/3 of the time. The production of 1000 kg of pumpkin requires absorption of nitrogen (n) of 3.5 to 5.5 kg, phosphorus (p2o5) of 1.5 to 2.2 kg, and potassium (k2o) of 5.3 to 7.29 kg. Pumpkins respond well to organic fertilizers such as manure and compost.

In the early stage of growth, the pumpkin has too much nitrogen fertilizer, which is easy to cause stems and leaves to grow long, and the head melon is easy to fall off; too late application of nitrogen fertilizer affects fruit expansion.
