NUTRIENT UPTAKE,SOIL AND PLANT NUTRIENT CONTENTS,AND YIELD COMPONENTS OF WHEAT PLANTS UNDER DIFFERENT PLANTING SYSTEMS AND VARIOUS IRRIGATION FREQUENCIES

The effects of seed bed shaping on nutrient variation in soil and plant under two different irrigation intervals were investigated on wheat (Triticum asetivum L.) plants with a split plot design in a field plot in Zahak Agricultural Research Station in Sistan province in 2005. Irrigations after 80 and 160 mm evaporation from class A evaporation pan were used as main plots. Flat surface irrigation, single, triple, and 6-row beds with four replications were subplots. Total soil nitrogen (N), available phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sodium (Na) were measured in a 30 cm depth top layer at five sampling times. Shoot samples were analyzed for N, P, K, Ca, Mg and Na. Results showed that the 3-row and the 6-row beds with more frequent irrigation (shorter irrigation interval) increased soil solution sodium content in beds resulting in increased plant sodium absorption. With the 3-row and the 6-row beds, increased solution sodium concentration in soil increased solution ionic strength, dissolution of lime and hence soluble Ca and Mg. With the more frequent irrigation (shorter irrigation interval), only grain nitrogen and sodium contents were increased with no change in the absorption of other nutrients. The shoot N, P, and K uptake with more frequent irrigation (shorter irrigation interval) was greater, however the grain P and K uptakes were similar with the less frequent irrigation (longer irrigation interval), suggesting a lack of transfer from other tissues to grain. The transfer of nitrogen and all other major elements from other tissues to grain was greatest with single row bed with both irrigation intervals, suggesting grain yield might not have been affected by a greater N, P and K fertilizer application. A key to grain yield increase with a more frequent irrigation (shorter irrigation interval) might be using a limiting micronutrient, effective in major nutrients transfer to grain from the other plant tissues or a bed shaping method enhancing its uptake.     

Improved DDR algorithm in media stream scheduling

Fuzzy control variable weight method of multi-factor decision-making adaptive deficit round robin scheduling algorithm (VWADRR), an improved deficit round robin(DRR) scheduling algorithm is put forward. It’s used in the circumstance of scheduling multiple multi-media data streams. It bases on multi-factor decision-making in the fuzzy control theory, specific to the use of the variable weight method. It’s adaptive for output channel bandwidth and buffer size of each input queues. Variable weight method makes decisions based on these two factors, that is, to determine the QN as variable in DRR. Considering the time of each packet sent, it reduces the packet delay. It effective uses buffers and bandwidth in the heavy network traffic situation, significantly reduces the possibility of buffer depletion, also smoothes burst.

做形温度对名优祁红品质形成的影响

为研究名优祁红做形工艺中不同除湿与造型温度对成茶品质的影响,除湿设烘干器100℃热风烘坯和电炒锅高温(180±5)℃、中温(160±5)℃、低温(140±5)℃炒坯4组,造型锅温设高(120±5)℃、中(100±5)℃、低(80±5)℃ 3组。对茶样的感官审评和生化成分测定分析表明：不同除湿温度对茶样的汤色和叶底影响显著,对茶红素（TR）和茶褐素（TB）含量影响极显著;不同造型温度对茶样的感官品质和生化成分含量影响不显著。烘坯做形比炒坯做形工效高,茶叶品质与中温炒坯做形茶相当,且以中温造型茶样较优;炒坯做形以中温除湿与中温造型茶样为好,低温炒坯除湿茶样的品质较差,高温炒坯除湿掌控不佳时茶样易出现高火的情况。因此,名优祁红做形工艺最佳温控组合为100℃热风烘坯或(160±5)℃炒坯除湿、(100±5)℃造型。
