The transformation of agricultural scientific and technological achievements is different because of different management modes and achievement types. Based on typical cases of scientific and technological innovation and achievement transformation in transformed institutes, we analyzed the mode and problems of transformation of scientific and technological achievements in enterprises. The methods were also proposed to solve these problems. [ABSTRACT FROM AUTHOR]

The water-fertilizer (NP) coupling field experiment for oilseed sunflower was conducted in the drought of middle ningxia under the condition of drip irrigation by “312-D”saturation optimum design. The regressive maths model was set up based on the oilseed sunflower yield. Analysis showed that the effects among these factors were positive on the oilseed sunflower yield with the influenced order as water>N>P, interaction effects influenced order as N and water>NP>P and water, and P and water was negative. The optimum dosage combinations of water-fertilizer coupling: the dosage of N were 248. 03 kg / hm², P2O5 were 104. 06 kg / hm², K2O 60 kg / hm², irrigation was 888. 05 m³ / hm². Yield reached 4 918. 15 kg / hm², than local yield and income of oilseed sunflower increased by 29. 4% and 5 287 yuan / hm². [ABSTRACT FROM AUTHOR]
