Indonesian farmers sometimes apply high rate of urea up to 500 kg urea/ha to rice which promote lodging and disease incidence. Potassium chloride and ammonium sulphate are relatively new materials for farmers and the adoption is 60% for KCl and 61 % for ammonium sulphate.

平衡施肥这项措施是1985年政府提出的，包括氮，磷，钾和硫之间的平衡，印尼农民在水稻上氮肥用量过高，有时达500公斤尿素/公顷，这样使倒伏和病虫害加重，氯化钾和硫酸铵对农民来说是二种新型肥料，只有60%的农民施用氯化钾，61%的农民施用硫铵。

4H was the best time of bovine oocyte activationin the 6-DAMP, and the cleavage rates and blastula rates could reach 85.1% and 26.8%. 4. IVF-100 was used in vitro fertilization, because IVF-100 was not needed to prepare usually,store conveniently, and gain a higher cleavage rates. After the oocytes have matured for 20h, theywere digested by permease and treated with suctionpipe.

由于IVF-100无需经常配制、保存方便且可以获得较高的卵裂率，所以本实验采用IVF-100为受精液，卵母细胞成熟20小时后采用透酶+口吸管消化的方法处理，获得了较好的受精效果，卵裂率可达(76.8％)。

He describes the effective pollination periodas the longevity of the ovules minus the time lag between pollination and fertilization.

他把有效的授粉阶段描述为胚珠的寿命减去授粉和受精之间的时间段。
