The results show that the optimal parameters of esterification are as follows: 4% of SO42-/ZrO2, molar ratio of methanol to litsea cubeba kernel oil 101, 68 ℃ of reaction temperature and 4 h of reaction time, the acid value decreases to 2.52 mg/g. Compared with the traditional acidic-catalyzed method, this method has the advantages of no acid proof equipment, easy to recycle catalyst and no acidic waste water emission. The optimal parameters of transesterification are as follows: 25 ℃ of reaction temperature, 0.5% of hexadecyl-trimethyl-ammonium bromide, 1% of NaOH, molar ratio of methanol to the oil 61 and 15 min of reaction time. The ester exchanging rate is 97.6%. This method adopts phase transfer catalyst and produces industry prospect, which has many advantages such as energy-saving and time-saving under room temperature.

Thereinto, drip irrigation is divided into three treatments of different ration. Tectorial and untectorial treatment are adopted to semifixation spray irrigation. At the same time, seepage-preventing trial is done. By study of one growth season, it shows that the indexes, Comparing with flood irrigation, water-saving technique has the effect of increasing production and harvest, economizing water, energy sources and field, saving work, time and power. It has best significance difference among unit yield of using different irrigation ways. The highest yield is in irrigation treatment of 80% field moisture capacity, it is secondary in seepage-preventing ditch irrigation treatment and is the lowest in spray irrigation treatment. Drip irrigation increase yield 4.0%~25.9%,Seepage-preventing ditch irrigation increase yield 17.5%, and spray irrigation decrease yield 22.4～37.8% comparing with flood irrigation. The effect to yield is obvious in drip irrigation treatment of different irrigation ration.

不同灌溉方式间单位产量存在显著差异，80％田间持水量灌溉处理产量最高，防渗渠畦灌次之，喷灌的产量最低；与土渠漫灌单位产量相比，滴灌增产4.0％～25.9％；防渗渠畦灌增产17.5％；喷灌产量下降22.4％～37.8％；滴灌试验中不同灌溉处理对产量的影响显著，随着灌溉定额的减少，产量随之下降，主要原因是60％田间持水量的灌溉处理限制了棉株的生长发育，降低了产量；不同灌溉方式的灌溉定额与绿洲内土渠漫灌平均灌溉定额相比，滴灌节水47.7％～54.4％，防渗渠畦灌节水38.56％，喷灌节水58.2％；滴灌、喷灌及防渗渠畦灌与土渠漫灌相比分别省工16.2％、25.1％和3.6％；滴灌和喷灌较防渗渠畦和土渠漫灌节地约5％～7％；从净收益来看，防渗渠畦灌较土渠漫灌经济效益提高了34.2％，滴灌提高了9.8％～48.2％，喷灌则下降了23.8％和44.7％；而且采用不同灌溉方式种植棉花，对于成铃率、衣指、衣分、纤维长度、产量等指标，滴灌要优于喷灌和防渗渠畦灌；而成铃数、种子数、铃重、籽指等指标，滴灌、喷灌均小于防渗渠畦灌。

The water-saving technologies in field are researched and concerned relatively weak,especially in the water deficit conditions,how to utilize the synthesis effects of water and fertilizer,increase the efficient utilization of soil water in saline soil,which are researched unprofound,the mechanism unclear,cant adapt the time requirements of agricultural water-saving.
