近年来,山东保护地厚皮甜瓜育种取得了突破性进展,但保护地制种技术尚未过关,致使制种产量低,效益差。产量最低时仅为2kg/(666.7m~2)。自1999年春季开始,我们开展了厚皮甜瓜制种技术的研究,改春季制种为秋季制种,使制种产量大幅度提高,每666.7m~2(亩)产量达8～10kg。其关键技术如下。一、制种季节近两年来的春秋制种对比试验结果表明,秋季制种比春季制种种子产量提高1倍以上,且制种成本每666.7m~2低1200元以上。平均1kg的制种成本降低400多元。故厚皮甜瓜的制种安排在秋季为宜。
In recent years, Shandong breed muskmelon breeding groundbreaking has made a breakthrough, but the protection of seed production technology has not been clearance, resulting in low seed production, poor efficiency. The lowest yield is only 2kg / (666.7m ~ 2). Since the spring of 1999, we conducted researches on the seed production techniques of muskmelon. The spring seed production was changed to autumn seed production, which greatly increased the seed yield. The yield per 666.7m ~ 2 (mu) reached 8 ~ 10kg. The key technologies are as follows. First, the seed production season in the past two years of spring and autumn seed production comparison test results show that seed production in autumn than the spring seed production increased more than 1 times, and seed production costs per 666.7m ~ 2 low 1200 yuan. The average production cost of 1kg is reduced by 400 yuan. Therefore, the production of muskmelon seed arrangement in the autumn is appropriate.
