不同作物吸收营养元素数量和比例差异很大,而不同土壤所能提供的营养元素亦有差别.因此,根据不同土壤能提供的营养元素水平和不同作物需要营养元素特点研制专用肥料是十分必要的.本研究的目的在于了解施用在甜瓜专用肥中加入含有多种成分的腐植酸后,对甜瓜产量及品质的影响.据研究,甜瓜吸收的N:P_2O_5:K_2O大体是1:0.74:1.97.而新疆甜瓜大多种植在含速效钾丰富的土壤上(如灌淤土、棕漠土、草 The quantity and proportion of nutrient elements absorbed by different crops are quite different, and the nutrients that different soils can provide are also different, so it is very necessary to develop special fertilizers according to the level of nutrients that can be provided by different soils and the nutrient elements needed by different crops The purpose of this study is to understand the effects of adding humic acid with various ingredients on the yield and quality of musk melon after applying special fertilizers.According to the research, the absorption of N: P 2 O 5: K 2 O is about 1: 0.74: 1.97. Most Xinjiang melon is planted in the soil with quick-available potassium (such as irrigation soil, brown desert soil, grass
