沙果,又名大果子,在我场栽植数量较多。成熟的沙果色泽鲜艳,食用甘甜,是深受群众欢迎的小型杂果。但沙果成熟不一致,采前落果特别严重,高达50—70％。为防止沙果采前落果,我们于1984年进行了萘乙酸防止沙果采前落果试验。 Sand fruit, also known as large fruit, in my field planted a larger number. The ripe sandy fruit is brightly colored and eaten sweet, and is a small fruit well received by the masses. However, the sand is not consistent with ripening, especially serious before the harvest fruit, up to 50-70%. In order to prevent the fruit from falling before harvest, we carried out naphthalene acetic acid test in 1984 to prevent the falling of fruit before harvesting.
