he correlations between the spring tea yields and climatic factors at every ten days in March and April in two Tea Plantations were analyzed. Results showed that the spring tea yields before Grain Rain had close correlation with the mean temperature of the second and last ten days in March and sunshine hour of the second ten days in March, especially had close correlations with the complex climatic factors. A regression equation for forecast the production before Grain Rain of spring tea was established using these complex climatic factors.

pringness wheat, i.e Yangmai No.5 and Yangmai 158, were frequently suffered from late frost damage in the lower reaches of Yangtze River. The output of springness wheat reduced by late frost damage in warm winter if it is sowed before Oct. 20, but the yield is high and stable if it is sowed in early days of the late ten days of October.Yangmai 158 possesses better recovering ability than Yangmai No.5 when suffered from late frost, so it has less yield losses. It is beneficial to recovering of damaged springness wheat by fertilizer supplement. Pressing in winter or spring can prevent or lessen the late frost damage. Spreading manure has a good effect.

ased on the statistical data of maize sown at different times in winter in three years, the quantitative relationships of yield of wintersowing maize and its character with climate were analyzed. The results showed that the main meteorological factors affecting the yield of wintersowing miaze are the shortage of accumulated temperature and cold damage. Jointingheading was the most critical stadge in which cold damage affected the yield of wintersowing maize. The secondary critical stage affecting the yield of wintersowing maize was headingblossoming.

ccording to the growth curve of dry matter, the maximum accumulated quantity and accumulative rate of dry matter under the optimum climatic conditions were calculated by using iterative method. Then, based on the relationship between the rate of greenness and the rate of accumulated dry matter, the maximum greenness was derived as the standard greenness. The ratio between the 1.6th power of greenness per year and the 1.6th power of standard greenness is divided by temperature correcting coefficient, water coefficient can be obtained. It is a water coefficient that is used for calculation of the water supply status during the growing periods of corn.

sing the grass and meteorological observation data from four Animal husbandrymeteorological stations, the effects of waterheat condition on grass yield, grass growing period and grass withered period were analyzed. Finally, the grass yield simulation equations and climatic situation evaluation model of grass growth were obtained.

weatherecological model was established by analysing the relationship between the 10day increment of sugarcane growth in height (ΔH), sugar content, etc. and meteorological factors. Finaly, according to the threedimensional distribution of sugar output, the planting division of sugarcane at Panxi was determined.

he effects of soil moisture on abscission of squares and bolls in different stages and on fibre quality of cotton were studied in 1991~1995 under the conditions of water control. It was found that deficient or excessive soil moisture led to increase in abscission of squares and bolls and decrease in fiber quality. The soil moisture favorable to increasing squares and bolls and improving fibre qualities was 60~70 percent of field capacity. The abscission rate and its sensitivity to soil moisture are different at different stages. The sensitivity of abscission to soil moisture was more noticeable in fullflowering to beginning of bollopening stage than in other stages, especially in squaring stage. The maximum abscission rate was in the fullflowering to beginning of bollopening stage, then in the flowering to fullflowering stage, the third was in squaring to flowering and the minimum was in bollopening stage. The soil moisture favorable to increasing squares and bolls in these stages was 54, 68, 64 and 63 percent of field capacity respectively. The favorable soil moisture to increasing fibre length, improving fibre fineness and increasing fibre intensity was 65 to 75 percent of field capacity.
