The corn-fed seedlings have been promoted for many years, and some villagers always think that it is very troublesome and rare. However, the corn seedlings transplanted and transplanted, higher than the corn live broadcast, at least 15% more.
Let me talk about choosing a seedbed. In order to reduce the workload, in each of the soils where corn is to be planted, corn seedlings are cultivated. How many nests need to be planted in this plot? In this way, the transplanting is done nearby, eliminating the trouble of picking up the fat group from a distance. If the car of the fattening seedlings can be leveled, it is of course better. It doesn't matter if it can't be leveled, as long as there are no stones in the mud.
Let's make a seedbed. In order not to waste material, the general film is 6 feet wide and the car has a 4 foot 5 or so (because the film is arched). The length of the car is determined by how many fat groups you make. Try to make the soil fine and flat, even if it is oblique soil, it is best to follow the soil obliquely, so that the fat group is placed and the fertilizer is even.
Next is the fat group production. Nearly 750 to 800 kg of nutritious soil is planted in an acre. Nutrient soil should not be mixed with weeds or stones. To prepare 100 kg of nutrient soil, 60 kg of topsoil, 35 kg of composted compost, 3 to 4 kg of plant ash, 1 to 2 kg of phosphate fertilizer, about 70 kg of decomposed pig manure to 70 kg of water, and mixed with soil for more than one day. Can do fat group. The role of fermentation is to disperse the mud and make the fertilizer mix with the mud to avoid hard mud. How much soil is needed in an acre, depending on the soil quality and demand. Then, the prepared nutritious soil is hand-kneaded into a duck egg-sized fat group or a small group of soup balls of appropriate size can be used to make a group; pinch or smash a group of neatly placed in a seedbed, and then use a finger Or a wooden stick to a small hole about 2 cm deep.
Finally, the soil is planted. Put two germinated seeds into each fat group. After the release, use a sieve to sieve more than half of the decomposed piles of fine soil cover, and cover them to the non-fat. Then, the film on the arch cover is complete.
After the nursery, the temperature is too high, as long as it does not dry, no fertilization is required.
It is necessary to pay attention to transplanting at the right time. It is best to transplant the two leaves and one heart; if you plant it, you will not be able to pass the sun. If you plant it, it will always change, and it may affect the output. In addition, when transplanting, the base fertilizer is applied. It is best to apply the bottom fertilizer and then cover the soil with a thin layer of soil and then put the corn seedlings into a group, so that the fertilizer group is not directly exposed to the fertilizer, so as not to burn the roots.
Drum brush is divided into long hair, medium hair, short hair three kinds, its performance is the length of the drum brush hair, rather than the thickness and length of the drum itself, brush hair is usually divided into wool and chemical fiber two kinds.
Different rollers will brush different effects, long hair rollers will brush out some fine texture, concave and convex feeling, similar to the texture effect. The paint surface after short wool roller besmear is more uniform, smooth, without concave and convex feeling, in the wool is between the two.
Roller brush is mostly made of wool and foam plastic, which can be divided into paint drum brush, hair drawing drum brush, floor paint drum brush, flat coating drum brush, etc., mainly used for large-area paint rolling in architectural decoration engineering. And can be used for coating and rolling all kinds of paint, such as: latex paint, anti-rust paint, internal and external wall paint, wallpaper glue, etc.
Note:
The use of drum brush as long as the straight brush can be wiped, if you want to daub evenly, the drum is best in the paint bucket to be fully absorbed, and then take out a few rolling on the inclined plane, press out the excess paint and then begin to brush the wall.
