Pre-planting training eight to eight
1. Transplanted seedlings should be planted. Do not use bare root seedlings
Because bare-rooted seedlings and transplanted seedlings have serious root damage during seedling raising, they are prone to root rot, and survival is difficult. If dry weather is encountered after transplanting, the survival rate will be lower, resulting in economic losses. The planting density should be low, the medium-large seedlings transplanted for 2-5 years, low density, easy to raise seedlings, large mud masses, less root damage, mud mass should be controlled at about 10 times the diameter of the stem, which is not only easy to survive, easy Management, provincial labor, rapid growth, and early production, economic returns high and fast.
2, to choose the early leaf type, do not choose the long leaf species
Because the fine-leaf cilantro varieties are excellent, they are put into production early, with high yield and good stability. As a matter of fact, the approval of the Chinese torreya is only fine, and people call it "Yushanguo". It is characterized by its early maturity, good quality, slender core, and pointed ends. The long-leaved pods are relatively late, harvesting is also late, and the production cycle is long. Therefore, a variety of finesse should be planted and the density can be relatively high.
3, pay attention to the direction, do not change to
Because the leaves of the citron have photosynthesis on the front and the leaves are breathing on the front, most of the leaves should be sunny when planting. That is, the relatively good side of the scent should be within 30 degrees to the south west, so it is not only easy to survive, but also grows. fast.
4, to maintain the original depth, not too shallow.
Seedlings should have a depth of 2-3 centimeters higher than the original cover soil when they have a good depth of fill. This will allow the roots to breathe and absorb nutrients when the rain returns to its original depth.
5, to fill the light pull, do not pan root
When backfilling soil, it is necessary to pull lightly while filling up. Normally about 70% of the filling time, the seedlings will be lifted upwards, so that the soil will naturally slip down, so that the roots will naturally have upper and lower levels, do not let the root plate fold in the same plane. Internally, the root system is naturally stretched, which is conducive to survival and rapid growth.
6, to be gentle and practical, do not tap
When seedlings are generally used down-to-earth, do not use a mallet to tap hard to avoid damage to seedling roots affect the survival. In the case of large seedlings with muddy masses, the mud shall be placed first to make the tree straight, and then the soil shall be filled with the lower part. Then the soil shall be filled and the soil shall be filled with solid soil. Do not step on the mudstone to facilitate rapid growth. .
7, to use fertilizer properly, not excessive
When sowing, high-quality phosphate fertilizer (calcium magnesium phosphate fertilizer) is applied around the root system, and organic fertilizer and other chemical fertilizers that have just been slaughtered are not used. With mature organic fertilizers applied to the roots or surfaces of the seedlings, the fertilizer should be avoided. If there is no mature cake fertilizer and bar fertilizer, the number of high-quality compound fertilizers should be less.
8, to match male and female, do not only plant female seedlings
Because the male trees bloom relatively slowly, the pollen of the short trees is not easy to spread, so when selecting the male trees, all kinds of early, middle and late varieties of flowering should be selected. The proportion is about 1-3%, and the proportion of sown area is smaller. Properly higher, sometimes it should reach 10%. For example, if 30 female flowers are planted, at least one early, middle, and late male flower should be selected. This is not excessive but rather less.
