对普通番茄果实非离株测产研究

CALCULATION YIELD OF COMMON TOMATO FRUITS BEFORE DE-PLANT

1988～1990年,对不同品种、不同海拔、不同土壤、不同地势的普遍番茄成熟期或半成熟期果实的研究结果表明,果实横径、纵径、果形指数、纵横乘积、果实数量等与果实重量有一定的相关性,从而建立了直线回归方程。经对普通番茄果实进行非离株估(测)产结果,经现场验证,实际测定产量与公式估测产量误差范围仅为±2.82％至±7.87％。

During 1988 to 1990 the yieid evaluation method of tomato fruits in ripe period or half ripe period sampled from different varieties,different elevation, different soil,and different features of places had been studied. The results showed that the tomato fruit hroizontal and vertical diameter, the fruit shap index, the horizontal and vertical product and the last numbers of fruit are relative to the weight of the fruit. The interrelationship helped us to set up a straight line regressive equation through calculation. Compared the estimating yield determined by this equation with the actual result is only a little different. The error is from ±2.82% to ±7.87% below the estimating target ±15%.
