The key points of spring and autumn gardens

Jujube is a unique tree species in China and has been planted for thousands of years in our country. Most of the traditional plantings are sparsely planted in the Qiangao stem-shaped Qiao-type variety, and they can enter the high-yield period after more than 10 years. Today, the traditional model is far from the needs of the development of science and technology, and the dense-dwarf cultivation technology has become a hot spot for promotion. In the research on the growth characteristics of jujube trees, I discovered that jujube trees with wild jujube as an anvil graft are stable in dwarfing traits and are more suitable for dense planting. The promotion and improvement of dwarf management technology has concluded that the technical points of spring and autumn of Miao Miao in Miao-Xia Park are “digging pits (grooves), irrigation, planting, short cutting, covering soil, and filming†to promote the root healing of jujube seedlings. To improve survival and ensure good growth for the first year of growth, we can receive the effect of "repaying money when the jujube tree is in year."
Ditching (ditch) Determine the size of the pit or the width of the ditch according to the size of the jujube root system. The general pit is 40-60 cm square, and the trench is 40-60 cm wide and deep. When digging pits or trenches, the surface living soil is separated from the deep dead soil.
Irrigation of the seedlings into the jujube seedling roots soaked in water for 24 hours, so that the plant suck enough water, and then lOO0ppm naphthalene acetic acid or hydrazine butyrate or rooting powder 50Oppm solution rooting 5-10 seconds. If the rooting water is poured after the planting, the water shall be covered and the earth shall be covered after the water seeps. Autumn planting seedlings in winter is better.
If there are conditions before colonization and planting, the pit may be filled with mature organic fertilizer or phosphate fertilizer mixed with the topsoil. The straw may also be filled with proper amount of straw, and the main root or lateral root of the damage of the planting seedling may be trimmed after cutting to reduce the wound surface. , Open cultivation garden according to strains, line 1x2 meters, 15x2 meters or lx3 meters, greenhouse according to specifications of 0.6xl meters jujube seedlings into the pit (ditch), first fill in the topsoil, then add deep soil to the grafting site, Slightly upward to raise the seedlings to make the roots stretch, practical filling, remember that "deep not prosperous, too shallow live."
After the short-term planting, leave three or four full shoots above the grafting site, 10-40 cm from the ground (short in winter and spring windy area, as short as 10 centimeters), then use plastic strips to tightly cut the wound or use Cover the wound with paint to prevent loss of water and ensure moisture supply and shoot growth during the seedling period.
The jujube seedlings planted in the northern high-jujube-cold zone of the Gaitu fall in the autumn after the planting and short-cutting, and the seedling rods were sealed and overwintered in mounds to prevent hares and other foraging and to prevent the winter and spring dry winds from draining the above-ground part of the liver after the next year. Plane to mound.
In the spring of spring, seedless shoots or spring seedlings must be planted with mulching, and they must be hydrated and warmed, and the wound healing and root development of the root system must be facilitated to shorten the seedling period and promote seedling growth.
Dwarf jujube garden or chaotic temperature shed spring and autumn planting seedlings, attention should not be excessive fertilizer, water irrigation should be moderate, seedlings should be low, fertilizer damage, water damage and high seedling consumption is a major cause of dead seedlings. To improve the survival rate of jujube seedlings, in addition to operating according to the main points of planting techniques, the autumn seedlings are generally shorter than the spring seedlings, and their hair roots are faster. The survival rate of spring planting seedlings is higher by more than 15%; the branching is early and the branch length is 15 centimeters; the fruiting rate is doubled in the coming year; the plant height at the time of decrepitude is about 150 centimeters, which is about 50 centimeters higher than the spring planting seedlings. Therefore, it is best to choose the autumn garden and garden. The good growth of the first growing year will enable the investment to be recovered in the next year, with a lot of returns, and ensure the high efficiency of the three-year high yield period. In this way, business opportunities will not be lost and the times will advance. The prospects are promising.
