Pear tree seedlings - What techniques do you need to grasp?
Pingdu City Star Garden Garden continues to dedicate 21st century - famous, excellent, special, new and other fruit seedlings, seeds and scion of a variety of fruit trees. Suitable for northern and southern regions
There are varieties, poor households and disabled people purchase 30% discount. This field is a breeding center for the promotion of famous varieties. It is a farmer and a company company.
There are more than ten million fruit tree seedlings and more than 100 species of green seedlings. Because of the credibility and practicality of this field, there have never been too many advertisements in this field, nor have we paid for large signboards, etc.
Since the seedlings were raised in 1979, the various seedlings that were raised every year were in short supply.
What skills do you need to acquire seedlings? Starlight Gardening answers you:
First, to grasp the different biological characteristics of seedlings with different seedling characteristics, we must focus on the characteristics of seedlings, pay attention to the combination of practice, through the seedling test, the clone
According to the forest test and regionalization attempt, etc., it is suitable for suitable land, not blindly introduced. Pear tree seedlings are bred according to the characteristics of seedling varieties, which is to improve the survival rate of seedlings, grab
The key link in the market.
Second, the choice of nursery land is the so-called selection of nursery land should be selected to facilitate irrigation and drainage, soil fertility, loose soil, the quality of the nursery, a great impact on the growth of seedlings
, Such as poor choice of nursery will cause serious results.
1. Do not pay attention to the selection of nurseries, blindly positioning, not reach the water, heat, nourishment, and gas conditions required for the growth of seedlings, so that the seedlings are stagnant;
Seedling phenomenon, even if the amount of fertilizer is increased, it will not be able to achieve the desired effect;
2. Pay attention to fertilizing and improving the soil, so that the soil structure changes, the nutrients are reduced, and thus the growth of seedlings is affected. Pear seedling price
Third, rational fertilization According to the nature of soil fertilization, in order to promote the principle of root development of seedlings, nitrogen, phosphorus, potash fertilizer and organic fertilizer reasonable application, not only save labor
Force and time, but also can improve fertilizer efficiency, reduce nitrogen leaching, increase soil organic matter content. Pear tree seedling manufacturers in general, the amount of basal fertilizer should account for
60% of the total amount of fertilizer, and 40% of the top-dressing fertilizer at the seedling stage, and the top-dressing in the seedling stage should be applied in accordance with the principle of “looking for fat at the root and no fat at the rootâ€.
Fourth, if seed and seed strips are treated with sexual reproduction, they should be netted first before sowing, since the seeds are often collected from the mother tree and the fruits are much more impurities. Screens can be used for the net seed treatment.
After sieving, rinse with water. Second, it should be disinfected. Disinfection can use drugs or lime water. Again, germination should be carried out and the germination treatment should be carried out in the greenhouse. If
After vegetative propagation, the cuttings must be stored before the cuttings. The method is to cut and balance the cut strips symmetrically in the order of coarse and fine, and store them by the method of digging and storage. dig
The cellar depth is generally between 50 cm and 70 cm. Reverse the polarity of the strips during storage so that the base of the root is facing upwards. Storage time depends on the characteristics of seedling varieties.
The principle of forming adventitious roots, restoring callus, and controlling sprouting at the base of the species.
