Alias: the country
Section: [dean]
Latin, english: sophora japoI'm sorry, nina linn.
Characteristics: leave the leaves on the wood, the crown ball of the country's herbs is large, the leaves are thick, the flowers are long and the shade is covered. The women and men, primers, butterflies, yellow and white, blooming in july-august, ripe fruit in november, berries in meat, beads in the form of curds, drying up when they mature, often hanging trees, and never winter. Seeds weigh 125 g per 1,000, with a gerontization rate of 70-85 per cent per kilo of approximately 8,000. The seed-dry collection has the capacity to last longer than 2-3 years。
Distribution: in the northern part of the country, cultivation is now practised throughout the country. It is common for the north chinese plain to grow at an altitude of 1,000 metres。
Growth characteristics: sex is cold-resistant, sun-sun-skinned, cloud-resistant and drought-resistant, poorly grown in low-lying water, deep roots, less demanding soil, less infertile, lime and light saline (about 0. 15 per cent salt). However, it is best to grow in wet, fertile, deep, well-watered sandy soils。
Main values: stronger liveness, hard materials, elasticity, texture, ease of processing, corrosive resistance, chromosomes of buds, potable fruit, seeds, etc. It is also wind-proof sand, with wood and trees used in economic forests, which are good shade trees and sidewalk trees in urban and rural areas。
Cultivation techniques: mainly sowing reproduction, can also be plugged in. In spring, 24 hours of water immersion at 85-90 degrees and 1-2 additional treatments of excess hard grains are used before seeding, due to the fact that the skins are fenced with cells. Seeds expand to sow. It is 20-25 cm long, is 1. 5-2 cm thick, is 8-10 kg per acre seeding, 7-10 days of seedlings are produced, and the seedlings are planted in a rational manner to prevent the convulsion of trees, usually 6-8 saplings per metre and up to 1 metre per year. In the early spring, it is also possible to concentrate on nutrition and then transplant seedlings. The country's budding power is such that if the seedlings are bred to form a good dry form, they can dry in the early spring of the second year, increasing the distance of the strain, which is 3-4 metres high, the trunks are straight and the trees smooth。
