The effect of soil conditioner on the soil fertility and yield of cassava
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 2
Abstract
"Soil conditioner consists of agricultural super absorbent polymers，and is rich in organic matter， natural peat humic acid as the main raw material，or other organic matter with biological active ingredient and nutrition elements，processed by science and technology products. This study discussed the effect of soil conditioner on the growth and development of cassava，and provided a theoretical basis for the application of soil conditioner in cassava production. The experiment was conducted from April 2016 to January 2017，with the variety of cassava Xinxuan048 as the materials，respectively 0 kg/hm2，450 kg/hm2 ，900 kg/hm2，1 350 kg/hm2 as the four treatments， Data collection was conducted in the seedling stage of cassava，root formation stage，root expansion stage and process maturity phase.Main determination of cassava germination rate，plant height，stem diameter，leaf number， root number，root length and other agronomic traits，and the determination of soil water content，bulk density， porosity，such as nitrogen，phosphorus and potassium content，organic matter content index. Results showed that soil conditioner can increase soil porosity and water retention，increase soil organic matter，nitrogen，phosphorus and potassium content，thereby promoting cassava germination，growth and soil nutrient absorption，increase production of cassava."
