法国李干的经济价值,取决于果粒的大小,而影响果粒大小的主要因子是树身果实载量的多寡,凡是树身的载量重,果实可溶性固形物低,果粒就小,鲜果的固形物低,则晒干率也低,相反,树身的载量轻,可溶性固形物高,果粒就大,晒干率就高,价值就大。虽说树的产量高低,不因果实载量多少而受到很大影响,但果粒大小却和树的载量有着密切关系。前人的试验结果指出,乙烯利对若干果树包括法国李可以起到疏果作用。当结果初期对大量结果的法国李采用乙烯利叶面喷布,可以降低座果,改进果粒大小。可是在上一年的生长季节,李果工业的产量预测和按果粒大小作价的规定订得太晚,致使栽培者不能获得采用此项措施的机会。1981年李果工业决定,把市上出售李果的最小果粒标准作为联邦政府的有关市场法
The economic value of dried plum is dependent on the size of the fruit. The main factor affecting the size of the fruit is the amount of fruit load on the tree. Where the body weight is heavy, the soluble solid content is low, the fruit size is small, Low solids, the sun drying rate is also low, on the contrary, the body of the light load, soluble solids, fruit is large, dry rate is high, the value is large. Although the yield of the tree is not greatly affected by the amount of causal load, the size of the fruit is closely related to the load of the tree. Previous experimental results indicate that ethephon can play a role in fruit thinning for several fruit trees, including French plum. When the results of the early results of a large number of French Li ethephon spray, you can reduce the fruit, improve fruit size. However, in the growing season of the previous year, Li Guo’s production forecast and price-by-grain provisions were set too late, leaving cultivers with no chance of adopting the measure. In 1981, Li Guo Industrial decided that the minimum standard for fruit grains sold in the market should be regarded as the relevant market law of the federal government
