一、第一穗果果实僵果多每年8、9月份种植的秋茬西红柿,第一穗膨果总是很慢,僵果多,这是为啥呢?造成西红柿僵果的原因很多,但造成第一穗果实僵果特别多的主要原因有两点:1.花芽分化不良。西红柿花芽分化早而快,一般在幼苗具有2~3片真叶时进行第一穗花的花芽分化,4~5片真叶时第二穗花花芽分化。而这段时间正处于8、9月份的高温季节,棚温常高于35℃,造成花芽分化不良,出现僵果的几率大。2.点花时间过早。如果点花时间不当,过早易形成僵果,影响果实商品性。
First, the fruit of the first ear fruit stiff fruit 8,8 months each year planted autumn tomatoes, the first ear swelling is always very slow, stiff fruit and more, which is why? Stir-fried tomatoes caused by many reasons, but There are two main reasons for the particularly large number of the first ear fruits: 1. Poor flower bud differentiation. Tomato flower bud differentiation fast and early, usually when the seedlings have 2 to 3 true leaves flower bud differentiation when the first flower, 4 ~ 5 true leaves when the second flower bud differentiation. This period of time is in August and September in the hot season, shed temperature is often higher than 35 ℃, resulting in poor flower bud differentiation, the risk of stiff fruit big. 2. Spending time too early. If you spend time improperly, premature easy to form a stiff fruit, affecting the commercial fruit.
