日光温室春番茄留果穗数对前期产量的影响

The Effect of Fruits Number Left on the Yield of Spring Tomatoes in the Heliogreenhouse

目光温室春番茄留2，3，4穗果，探讨对花芽发育、前期产量、总产量和产值的影响。试验结果袁明，在留4穗果范围内，留果穗数对花芽发育和前期产量都没有影响；总产量和产值留4穗果的处理最高，它极显著高于留2穗果和留3穗果的处理，留3穗果和留2穗果的处理差异不显著，但总产量留3穗果比留2穗果有增加的趋势。日光温室春番茄留4穗果适宜。

By leaving 2, 3 or 4 fruits on spring tomatoes,the effect of fruits'number left was studied on the development of fruit bud,the yield in the prior stage,the total yield and the profit in the heliogreenhouse.The result shows that,within 4 fruits left,the number of fruits left has no obvious effect on the development of the fruit bud and the highest and signinficantly higher than those of 2 or 3 fruits left. There is no significant difference between 2 and 3 fruits left,but the total yield of 3 fruits left is a little higher than that of 2 fruits left. It is appropriate to leave 4 fruits on spring tomatoes in the heliogreenbouse.
