为探讨保水型控释肥对作物生长的影响,以普通控释肥处理为对照,以含保水剂质量分数分别为0.5%、1.0%、2.0%、3.0%的控释肥为不同处理,对番茄进行盆栽试验。结果表明:与对照相比,施加含保水剂质量分数为2.0%的控释肥的番茄生长特性较优,株高增加11.15%,茎粗增加9.24%,地上部生物量增加10.98%,须根数量增加7.09%,地下部生物量增加10.53%;保水型控释肥具有一定的保水功能,土壤中水质量分数提高2.47%。采用复合包膜工艺生产的保水型控释肥,可以调节土壤中水分的供应,促进作物的生长发育。
In order to explore the effect of water retaining controlled-release compound fertilizer on crop growth, a pot experiment of tomato is carried out with common controlled-release compound fertilizer treatment as control, and controlled-release compound fertilizer with mass fractions of 0.5%, 1.0%, 2.0% and 3.0% water retaining agent respectively as different treatments. The results show that compared with the control, the growth characteristics of tomato with controlled-release compound fertilizer with water retaining agent mass fraction of 2.0% are better. The plant height increases by 11.15%, the stem diameter increases by 9.24%, the aboveground biomass increases by 10.98%, the number of fibrous roots increases by 7.09%, and the underground biomass increases by 10.53%. The water retaining controlled-release compound fertilizer has a certain water retaining function, and the soil water content is increased by 2.47%. The water retaining controlled-release compound fertilizer produced by the composite coating process can regulate the supply of water in the soil and promote the growth and development of crops.
