Seedling management of Cymbidium (transplanting seedlings, squatting seedlings, dividing pots) and fertilization methods of edible fungi

The management of Clivia seedlings mentioned here refers to the seedlings after sowing, the seedlings are relatively small, and some maintenance precautions in the later stage. Generally speaking, it is relatively simple. The seedling management can be mainly divided into three parts: transplanting seedlings, squatting seedlings and transplanting in pots.

1. Transplantation of Clivia seedlings

After 50-60 days of seedling cultivation, the new roots of seedlings are 5-6cm long, and sharp leaf banks have grown, which is the best period for transplanting. The new roots grow too long, which will not be convenient for transplanting. The new roots will branch when they grow to 8cm, which is even more inconvenient for transplanting.(Remember that it is not transplanted out of the leaf bank, and it must reach a certain proportion, reaching about 60%). The advantages of transplanting at this time are:

1. With the leaf bank reference fruit, the direction of the true leaf can be identified.

2. Avoid multiple transplants affecting the growth of seedlings.

3, easy to transplant, small roots. Short, the new root will not exceed 8 cm and has not yet branched.

4. The seedlings grow fast in humus soil.

5, save time and effort, small damage.

Seedling method:

According to the marks made on the seedling closure, all the seedlings are picked up according to the variety classification. When picking up seedlings, pinch the lower part of the leaf bank with your thumb and forefinger and pull it out. Don't pinch the fruit and pull it out. It is easy to drop the fruit. The fruit is the nutrient irrigation for the seedlings. The later growth of the seedlings depends on him to provide nutrition.

Before seedling, prepare items;(1) prepare flowerpots;(2) seedling soil (humus soil 75% charcoal ash 7% buckwheat husk 5% stone 3%, seedling sawdust 10%); seedling sawdust mixed into humus soil is conducive to slow seedlings, but do not mix them, the bottom is not contaminated and reserved for another use, pot humus compaction (3) a chopstick.

seedling transplanting

1, with chopsticks hole, depth and length match, new roots more than 2 cm can see all the leaves of the bank transplanted in the humus soil.

2. Pay attention to several details when transplanting seedlings: (1) Transplant seedlings according to varieties,(2) 2--10 plants per pot,(I have 13 plants per pot because there are too many seedlings and there is no place to put them. The number of plants in each pot can be determined according to my actual situation)(3) Properly open the spacing, look horizontally into rows, stagger the front and rear plants, so as to facilitate the growth and lighting of the seedlings, and do not block the lighting of the seedlings at the back;(4) Classify them according to size, and do not transplant them in a pot of different sizes, which is inconvenient for management in the future;(5) Then carefully insert the fleshy roots of the seedlings and press the soil;(6) The fruits grow on the back of the leaves. When transplanting, look at the position of the fruit and seedlings, ensure that the fruit is in one direction, and the first leaf must be in one direction!

3, the new root less than 2 cm did not grow out of the leaf bank transplanting method (hundreds of seeds can not all grow the same length less than 2 cm). Compacting humus soil contained at the bottom of transplanted flowerpot, adding sawdust used for seedling raising without pollution at the bottom, the thickness of sawdust is determined by the length of new roots of transplanted seedlings, and the new roots cannot be directly contacted with humus soil, that is to say, the thickness of new roots should exceed 1.5cm. When seedlings grow out of leaf bank, new roots can grow into humus soil.

4. The seedlings have grown out of the leaf bank from sawdust. At this time, remove all sawdust and optimize. There are more than 10 fruits in the pot in the same direction. The rest can be gently rotated and corrected to ensure that the fruits are in one direction. Fill with humus and compact them until spring.

Second, dry cultivation squatting seedlings: the seedlings grow normally with an average of 1mm per day. When the seedlings grow to about 2 cm, control the water supply at the point. Dry cultivation for about 20 days makes the leaves of the seedlings thicker and the plants stronger, which is good for later transplanting and slowing seedlings.

Third, transplanting in pots:

When the first leaf of the plant grows to 5-8 cm, it can be divided into pots according to varieties and sizes. Choose a good pot and match the soil. Two to four plants can be planted in each pot. Two high-quality plants can also be transplanted according to the actual situation. Don't wait until April to change the soil. If the plant is too big, it is not easy to transplant. The seedling can be transplanted in February and March, which has no effect on the later growth of the seedling.

IV. Post-management:

Do not provide fertilizer within 30 days after transplanting seedlings, otherwise it will kill seedlings. After 30 days, observe whether seedlings are growing. If they grow well, they can be appropriately applied with light 70:1 liquid fertilizer once every 20 days. If they grow badly, do not fertilize them. Give them a chance to slow down seedlings. This is the same as people. Your health absorption function is good. Your body is bad. Big fish and big meat wait on you. Can you stand it?

Normal mature seeds sprout in about 10 days after sowing, leaf bank can grow in about 50 days, leaves 2-5 cm in about 90 days, and second leaves in 150 days. At this time, care must be taken carefully to ensure that they grow healthily and healthily. This is the same as animals. There is no healthy physique in hours, which has a great impact on later growth. Some seedlings are not as big as one year in 3 years. It is common. You should observe them frequently. Individual plants do not grow. It must be a problem. We all know that normal plants are growing every day. Normally, 4-6 leaves can grow from sowing for a full year. This is the standard. If the plants do not reach 4-6 leaves a year, verify that your cultivation is not in place and you still need to work hard.
