How to divide the seedlings of vegetables to improve the survival rate
To divide the seedlings of vegetables, it is necessary to prevent the seedlings from squeezing seedlings, expand the nutrition and light area of ​​the seedlings, and promote the seedlings to grow faster. However, split seedlings will inevitably cause different degrees of root-cutting, reduce root function, and inhibit the normal growth of seedlings. To ensure that seedlings restore as much as possible the root absorption function, the healthy growth of seedlings, its measures are as follows.
I. Timely seedlings
The pepper and eggplant seedlings should be grown within 40 to 60 days after sowing. Split seedlings start from 2 true leaves, and sub-seedlings should be controlled within 3 to 4 true leaves. Because the seedlings are relatively small, the seedling rate is high and the seedling age is too large, which affects flower bud differentiation, and each time the seedlings are divided, they are delayed for 5 to 6 days. 3 to 5 days before seedling separation, the seedbed should be cooled, ventilation should be increased, water must be controlled, and seedlings must be trained. Dividing the seedlings when they do edge digging seedlings, while arranging a small arch shed seedlings cover film, to prevent noon high temperature seedlings wilting. When seedlings are divided, they should concentrate their labor and time for row seedlings in order to facilitate the robust growth and management of young seedlings.
Second, the density is suitable
There is a close relationship between seedling density and yield. Within a certain range, with the increase in the distance from the seedlings, the yield in the previous period will be relatively increased, and the benefits will also increase substantially. The average pepper seedlings from 7 to 8 cm, eggplant 8 to 9 cm. If the seedbed is not tense, its seedling distance can reach 8 to 10 centimeters; the diameter of the seedlings of the nutrition seedlings can reach 8 to 10 centimeters, and the earth can be enriched with the earth to improve the moisturizing and heat preservation effect, which is beneficial for cultivating the strong seedlings and increasing the yield.
Third, seedling method
The seedlings should be watered in the first half of the seedlings, which is beneficial to dig seedlings and seedlings. Use shovels or shovels to dig seedlings. Digging seedlings requires 1 to 2 cm from the seedling roots. After excavating the seedlings, gently excavate most of the soil from the root and then place it in a basin or basket for drainage. Do not injure the shoots and take care of the cotyledons.
Immediately after the seedlings are excavated, the seedlings should be rowed, and in particular, the roots should be protected from the sun or be blown away by the wind. When separating the seedlings, it is best to separate the seedlings from the seedlings, remove diseased seedlings, insect-injured seedlings, and headless seedlings.
The seedlings should be in shallow rows, and the cotyledons usually have 1 to 2 cm unearthed as the standard. Row seedlings should be tightly rooted and the roots should be poured in time. The seedlings excavated on the day were lined up. If you can't finish in the morning, you can concentrate on soil and cover it with a cover to prevent dehydration and wilting, and finish it in the afternoon.

if you only have hearing loss in one ear, then you have unilateral hearing loss and you`re more likely to get all the support you need from a single hearing aid. You can wear a single unilateral hearing aid in your bad ear and hear normally with the other one. Because your other ear is functioning normally you will get all the benefits of binaural hearing with just one hearing device.
