所谓形态诊断就是通过对番茄形态的观察来判断植株的生长发育状况。进行正确有效的菜田管理,以取得较高的产量。番茄的形态诊断技术应分以下几个生育阶段进行。一、发芽期(种子、出苗——第1片真叶出现) 在一定的昼夜温差下,子叶大而宽,胚轴3厘米左右,是生长发育正常的标志。胚轴3厘米以上,子叶细长且小,是高温、高湿造成的徒长。反之如果胚轴过短子叶小,则说明低温干燥抑制了生长。
The so-called morphological diagnosis is through the observation of tomato morphology to determine the growth and development of plants. Proper and effective management of vegetable fields in order to achieve higher yields. Tomato morphological diagnosis techniques should be divided into the following stages of fertility. First, the germination period (seed, emergence - the first true leaves appear) at a certain temperature difference between day and night, cotyledons large and broad, hypocotyl 3 cm or so, is a sign of normal growth and development. Hypocotyl 3 cm above, cotyledons slender and small, is caused by high temperature, high humidity leggy. Conversely, if the hypocotyls are too short, the hypothermic drying inhibits the growth.
