1 soil preparation
Before Huanghua pear is cultivated, it is necessary to choose the soil environment suitable for its production. Therefore, soil preparation is particularly important in the cultivation techniques of Huanghua pear, which is the foundation of its healthy growth. First of all, we should choose the planting area of woodland. According to the characteristics of Huanghua pear, which likes light, temperature and deep roots, we choose to plant it in hills, Pingshan, low mountains and other places that are easily exposed to sunlight. In order to prevent floods, it is appropriate to control the altitude in mountainous areas. Because of its heat-loving characteristics, the selection and division of Huanghua pear planting sites must be controlled within 600 m, and only in this way can the basic conditions for planting Huanghua pear trees be met. Secondly, in the winter of the year before planting huanghuali, we should loosen the soil and open up wasteland, and dig holes to plant huanghuali seedlings on the basis of these work, so as to facilitate the smooth rooting and planting of huanghuali seedlings; Then, in the land preparation, the stand density of Huanghua pear seedling should be planned reasonably. Generally, the row spacing of seedlings is 3 m × 3 m, which is suitable for soil with rich water and good soil fertility. Aiming at the dry land area with low fertility and less water, the best planting density is 2 m × 2 m or 3 m × 2 m, which creates favorable conditions for Huanghua pear to absorb nutrients from fertilizer. Finally, the choice of planting period. In the whole process of soil preparation, March-April in spring is the best afforestation season for Huanghua pear cultivation at a specific time. This is the key point that should be paid attention to in the process of land preparation for Huanghua pear cultivation.
2 fertilization
Fertilization undoubtedly plays an extremely important role in the process of tree species cultivation. In the choice of fertilizer, it must be adjusted according to the growth state of tree species. Fertilizers mainly include calcium, magnesium, phosphorus and organic fertilizer (livestock manure, coarse grain residue, etc.). ), soil mixed fertilizer and pond sludge. In addition, in the process of fertilization, the fertilizer should be applied from the root of Huanghua pear, which requires that the fertilizer should be fully stirred and buried in the root of Huanghua pear, so that Huanghua pear can use and absorb the nutrients contained in the fertilizer more efficiently.
3 planting
In the cultivation process of Huanghua pear, planting is a key link directly related to the future growth of seedlings. First of all, when burying seedlings, we should ensure the integrity of the root system and ensure that it will not be destroyed by human beings when planting; Secondly, in the process of soil compaction, do not use violent actions such as pedaling to compact the soil. The soil compaction must be carried out patiently in strict accordance with the requirements of layered fill compaction to prevent the loose seedlings in the soil from being skewed due to rainwater backflow. Finally, according to the weather, water the buried part of the root to ensure its survival.
4 Tending management
To do a good job in tending management, we must first choose excellent young trees, and only excellent tree species can play a positive role in promoting the growth process of Huanghua pear; Secondly, check and fill the gaps in the seedlings. In the process of raising seedlings, the growth state of seedlings is inspected and observed one month after planting, and the missing part of seedlings is supplemented, so that the growth state of Huanghua pear is regular in the future growth; Then, we should do a good job of fertilizing seedlings. Supplementing fertilizer in time is the key to the healthy growth of Huanghua pear, which can meet the needs of its production. Finally, prune the branches of huanghuali regularly. In the process of planting tree species, poorly pruned branches can make Huang Huali grow stronger, which is beneficial to the shaping and growth of Huang Huali.
5 pest control
Huanghua pear is mainly poisoned by anthracnose and nevus. Therefore, in the cultivation of Huanghua pear, we must do a good job in pest control. The tree tops and leaves of Huanghua pear are prone to anthracnose, which makes the leaves of Huanghua pear appear brown circular spots. At the same time, the top of the tree will get darker and darker, and eventually it will dry up. Insecticides such as chlorothalonil can undoubtedly solve this problem. Therefore, it is necessary for breeders to spray pesticides on Huanghua pear once a week, and the total number of times is 2 ~ 3 times. On the other hand, Huanghua pear is vulnerable to black spot disease at seedling stage. This pest mainly occurs in the rainy season, which will cause damage to the branches, leaves and pods of Huanghua pear. For example, the leaves appear black and fall off seriously, which is extremely unfavorable to the growth of Huanghua pear seedlings. Therefore, it is necessary to do a good job in pest control of Huanghua pear.
