番茄授粉结束以后开始坐果并进入种子生长旺盛期,这个时期的管理直接影响到番茄制种的产量和质量。现把几项关键技术介绍如下: 1.合理配制养分 番茄种子生长需大量而全面的营养。据研究,番茄生长中每1000公斤果实需N3.18公斤、P0.74公斤、K4.83公斤。因此,氮、磷、钾必须合理配制才能满足植株对养分的需求。 在番茄制种过程中,幼苗期应以氮肥为主,促进叶面扩展。但在后期氮肥施用应适时适量,避免用量过大引起疯长和影响其它养分的吸收,诱发果实筋腐病,不利种子生产。一般
After the end of pollination, the tomato begins to sit and enter the vigorous growth of the seed. The management of this period directly affects the yield and quality of the tomato seed. Now introduce several key technologies are as follows: 1. Reasonable preparation of nutrients Tomato seed growth requires a large and comprehensive nutrition. According to the study, tomato growth needs N3.18 kg, P0.74 kg, K4.83 kg for every 1000 kg of fruit. Therefore, nitrogen, phosphorus, potassium must be properly formulated to meet plant nutrient requirements. In the tomato seed production process, the seedling should be nitrogen-based promotion of leaf expansion. However, in the late application of nitrogen should be timely and appropriate amount to avoid excessive consumption caused by soaring and affect the absorption of other nutrients, induced fruit tendon rot, adverse seed production. general
