The effects of inter-row green covering in vineyard with white clover (Trifolium repens),perennial ryegrass(Lolium perenne) and alfalfa(Medicago sat iva) on malolactic fermentation(MLF) of Cabernet Sauvignon claret were studied.

对不同行间生草处理酿造的赤霞珠干红葡萄酒进行苹果酸-乳酸发酵,结果表明:MLF后生草处理的葡萄酒平均每降1g酸pH值升高的幅度显著高于清耕(对照);总酸降低幅度以多年生黑麦草最高,紫花苜蓿最低;生草处理的葡萄酒挥发酸升高幅度均低于清耕;多年生黑麦草和白三叶草处理使MLF持续时间较清耕缩短,紫花苜蓿持续时间最长。

The main concepts of flight separation safety assessment are present:flight separation,separation minima,conflict,airmiss,and collision.

首先概述了飞行间隔安全评估研究中常用的概念,然后从REICH模型、交叉航路模型、概率论模型、随机分析模型、EVENT模型和RASRAM模型6种常用碰撞风险模型的角度,分析了各个模型的优缺点和各自的适用范围,分析结果表明飞行间隔安全评估中的关键问题为:模型的限制、管制意图和安全评价,并在此基础上分析了飞行间隔安全评估未来的研究方向。

行间覆膜节水技术集雨作用的研究

A research about the effects of covering film between furrows on dynamic of soil moisture in root zone and yield of maize was developed in Gannan country,Heilongjiang Province in 2007.

2007年在黑龙江省甘南县进行了行间覆膜对玉米根系层土壤水分动态及玉米产量影响的试验研究,在玉米全生育期,采用时域反射仪(TDR)对土壤水分指标进行观测,分析了玉米全生育期农田土壤水分动态变化过程。
