上海石刁柏留母茎栽培法对产量品级和茎枯病害发生的影响

EFFECT OF ASPARAGUS MOTHER STALK CULTURAL METHOD ON YIELD PRODUCT GRADE AND STEM BLIGHT INCIDENCE IN SHANGHAI

通过石刁柏留母茎栽培多种采收方式的试验，结果表明：合适的留母茎栽培法比传统栽培法产量提高１１５．８％，一级品嫩茎增加２０．５％，产值增加１２８．８％。留母茎栽培石刁柏的茎枯病发生过程分为前、后两个时期，故病害的发生流行不连续，加之前后两期间还更换茎株和清洁田园，因此有利于病害的防治。

This paper reports asparagus mother stalk cultural tests with different picking modes in Shanghai. The yield in the plots of reasonable mother stalk cultural mode increases by 115. 8% as compared to that in the plots of conventional cultural model the 1grade products in the former plots increase by 20. 5% and the output value increases by 128. 8% in comparison with the CK plots. Correlation between asparagus mother stalk cultural method and fluctuation of stem blight incidence affords us the basis in disease control.
