在贵州省内不同的土壤肥力条件下,用4种肥料,3种不同用量,共12个处理,作稻田肥效试验。施用结果表明:试验肥料的肥效为尿素(A4)>有机复合肥(A2)>无机复合肥(A3)>有机复合肥(A1),复合肥与尿素差异大,而有机复合肥与无机复合肥之间差异小。有机复合肥各处理,净产值均比尿素(CK2)低113.9~167元,而有机复合肥除个别用量与CK1同用量相当外,其余各处理均比无机复合肥(CK1)低35.3~64.5元。有机复合肥对水稻主要经济性状和米质无明显的影响,但可比尿素CK2提早水稻生育期4~6d,可以一定程度提高土壤中的水解N和有效K等。
Under different soil fertility conditions in Guizhou Province, four kinds of fertilizers, three different dosage, a total of 12 treatments for paddy field fertilizer efficiency test. The results showed that: the test fertilizer fertilizer efficiency for urea (A4)> organic compound fertilizer (A2)> inorganic compound fertilizer (A3)> organic compound fertilizer (A1), compound fertilizer and urea differences, and organic compound fertilizer and inorganic compound fertilizer The difference is small. Organic compound fertilizer treatment, the net output value of urea 113.9 ~ 167 yuan lower than urea (CK2), while the amount of organic compound fertilizer with CK1 with the same amount, the rest of the treatment than the inorganic compound fertilizer (CK1) low 35.3 ~ 64.5 yuan. Organic compound fertilizer had no significant effect on the main economic characters and rice quality of rice, but the growth period of rice could be 4 ~ 6 days earlier than that of urea CK2, which could increase the hydrolysis N and available K in soil to some extent.
