1. Arsenal plantations
The flower of the aphid is identical to that of the male and female, i. E., the single flower, with the latter leaf. The male is born in a soft line, and the female in a head line, and the male is born in a single year of twig, on the top of the middle or the top of the short branch, which is transmitted by a medium. Therefore, a herring garden should be configured with the same or similar variety of flowers, usually with three varieties, ranging from 5 to 6:1。
Temperature
Different types of thorium require different temperatures. O'hare is warm and wet. An average temperature of 13-15°c, absolute lowest - 10°c, and an extremely high temperature of 38°c. Pygmy species are more resistant to the cold than europeans and are suitable for average annual temperatures of 7. 5-13°c, with a minimum temperature of 30°c。
3. Light
The aphids are radiant plants and are generally required to have more than 2100 sunday hours per year, otherwise the buds are less formed and less productive。
Soil
The acacia is growing on fertile and aerobic sandy soil, especially in the case of pyrotechnics, which require high levels of soil, dry sand, clay, marshland, saline and low-lying lands. Pyro hybrids require soil ph of 6. 5-7. 5 and euro5-7。
5. Cultivation
The branches of the gills tend to take root, and they tend to take root. As a result, seedlings are usually cultivated by bar or incubation. In the early springs, a year of healthy growth was used, and in june, a year of tenderness was used as material. Weaning is used to grow seedlings, which are grown from flat to flat。
6. Measures to increase production
The sorghums are prone to flowering fruit and have a high rate of emptiness and inflammation. Main measures of prevention: 1 good parent tree is selected for breeding; 2 plants are set up with pollination trees supported by artificial pollination; 3 nutrition management is improved。
