Applied Ecotechnical Research on Lbao Slow-Release Water-Fertilizer-Nutrition Agent

L黚ao slow-release water-fertilizer-nutrition agent (LSWA) is a new and proven highly effective soil additive. This nutrient absorbent polymer dramatically conserves water and reduces fertilizer usage while significantly increasing plant and crop yield. There are numerous benefits that LSWA is engineered to produce, and moreover, with every new application new benefits are discovered. The versatility of this additive will undoubtedly lead to some new applications. LSWA crystals in the soil absorb hundreds of times their mass in water and then, upon demand, release the stored moisture regardless of the soil condition. Unlike previously used polymers, LSWA has great absorbability even under soil pressure, and maintains its absorbability in the presence of fertilizers and other water soluble additives. It is completely non-toxic, and has a lengthy effective period of seven to ten years. LSWA is extremely cost effective due to its low initial cost, the dramatic reduction in the number of watering cycles, the decrease of fertilizer usage and the increase in crop yield, as well as allowing utilization of previously unusable land. When LSWA crystals are added into the soil, irrigation schedule times can be reduced by more than 50%, and fertilizer usage reduced by up to 33%. In this paper, some basic researches on the basic properties of the soil additive are reported. Some applications are described by reference to a number of case studies. Finally, specific recommendations are given for the application rates and methods for a range of crops and soil conditions.

Control Effect of Slow-release, Long-acting and Multi-functional New Pesticides on Sugarcane Borders and Woolly Aphids

In order to select the long-acting,low toxic,low-risk and multi-functional new pesticides for the control of sugarcane borders and woolly aphids and precise and efficient application technology,the control effect of 10% monosultap · thiamethoxam granular formulation and 1% Bt · clothianidin granular formulation on sugarcane borders and woolly aphids were studied.The results showed that 10% monosultap·thiamethoxam GR and 1% Bt·clothianidin GR had good control effects on sugarcane borders and woolly aphids.They were ideal slow-release,long-acting,low toxic and multi-functional new pesticides used to control sugarcane borders and woolly aphids.They could be used alternately with other pesticides to delay the emergence and development of pest resistance to pesticides.The best dosage of the two pesticides in the field was 45 kg/hm^2.They could be mixed with fertilizer( 1200-1800 kg/hm^2),scattered in sugarcane ditches or at the base of sugarcane plants,and covered with soil or film from January to July.The control effect on dead heart seedlings damaged by borers could be up to above 79.2%,and the control effect on sugarcane woolly aphids could reach more than 98.8%.In comparison with the control group,the actual yield and sugar content of sugarcane increased by above 41 555 kg/hm^2 and 6.5% respectively.The application of slow-release,long-acting,strong systemic and multi-functional new agents with fertilizer around roots is convenient,precise and efficient,labor-saving,time-saving and environmentally friendly,and is worthy of being widely applied in sugarcane areas.
