coated-urea

基本解釋

The release characteristics of coated urea were determined by means of water marinating and soil incubation.
用水浸泡法和土壤培養(yǎng)法表征了包膜尿素的釋放特性,用掃描電子顯微鏡研究了包膜尿素的表面和截面形貌。
Experiments and researches are carried out on the nutrient release characteristics of polymer-sulphur coated urea (PSCU).
摘要對聚合物硫包尿素（簡稱PSCU）產(chǎn)品的養(yǎng)分釋放特性進(jìn)行了試驗研究。
Coated urea fertilizer is a new type fertilizer to improve fertilizer's usage rate and solve the environment pollution questions.
摘要包膜尿素肥料是提高肥料利用率，解決環(huán)境污染問題的一種新型肥料。
Coated urea application increased the activities of polyphenol oxidase, phosphatase, and urease, which were significantly correlated with soil nutrient factors.
結(jié)果表明，施用包膜控釋尿素比普通尿素能明顯提高土壤有機(jī)質(zhì)、全氮、堿解氮、硝態(tài)氮、銨態(tài)氮、速效鉀含量，降低了土壤速效磷含量；
Experiments for nutrient release of chitosan coated urea(CCU) were carried out to elucidate the effect of moisture on nutrient release characteristic of CCU.
探討了土壤中水分對殼聚糖包膜尿素(CCU)養(yǎng)分釋放特性的影響。結(jié)果表明:CCU具有很好的緩釋效果,養(yǎng)分釋放率與包膜內(nèi)水蒸氣壓差呈線性關(guān)系;
