夏天育苗成活率低怎么回事掌握这几点,提高幼苗成活率

时间:2019-07-26

Hello everyone, I am ‘’the farmer’s little friend’’, please follow my article, please pay attention, thank you!

Everyone knows that planting vegetables needs to be raised in advance, but it is difficult to ensure the survival rate of seedlings in summer. This is because the summer temperature is too high, and the seedlings are drought-tolerant and heat-resistant, plus various causes such as thunderstorms. of. Today, I would like to share with you the protection measures for summer seedlings to ensure the success rate of summer seedlings.

There are two ways to cultivate vegetable seedlings. One is to use organic soil to install a tray, and the other is to level the land to scatter seeds. Regardless of the type of nursery, it is necessary to pay attention to the prevention of high temperature in the summer breeding; anti-drought; rain-proof, this is to ensure that the cultivated seedlings can grow smoothly to transplanting and planting. Take blind seed as an example. This is the most common way of growing vegetables in various regions. In this area, when we use this kind of busy seed, we will prepare the sawdust in advance. This is used to cover the top of the seed, to ensure the moisture of the land, and the root of the seed is not high due to weather problems. With the question. There must be anti-high temperature measures on the sprinkled land, which requires the use of a sunshade net. (Plastic cloth is not recommended, and it must be shaded with black ink or muddy water.) If it is raised in a shed-like field, Cover the sunshade net on the shelf. If there is no shelf, use bamboo to form a semicircle to support the sunshade net. The sunshade net is used to block the sun from about 9:00 am to about 5:00 pm. This is the measure to protect the seedlings from the hot sun in the summer. The rest of the time is without rain. Do not cover the shade net.

xx在幼苗生长期,还需要保证幼苗的水分和养分。如果太干燥太干,不利于幼苗的生长,营养也不会跟上,幼苗生长缓慢,病情会增加。在浇地时合理使用肥料可以保证苗木的旺盛生长,也可以减少营养不良引起的苗木病害的减少。这种浇水在晚上和早上也是最好的。使用水溶性肥料可以更好地利用肥料,确保幼苗在中午有足够的水吸收。

在育苗期间,幼苗不能帮助下雨,这种防雨措施同样重要。由于幼苗较浅,它们无法抵抗雨水的冲刷。 (当浇注井时,它也会被少量的水慢慢侵染。)如果有强风和小雨,则没有防雨措施。由于雨和风,幼苗很容易死亡,雨水在育苗中非常重要。

上述措施是我现在用来培育幼苗的方法,这也确保幼苗可以安全地生长到移植。虽然它不是一种高科技的方法和措施,但如果特别饲养幼苗,成本会高得多,这会增加成本。虽然幼苗很难繁殖,但在移栽时可以捡到大的种子和幼苗。移植的第一件事是移植。这将缩短蔬菜与市场之间的时间差距。
