How to plant red bayberry seeds?

Red bayberry is an excellent tree species produced by the combination of landscaping and greening. it is a small tree or shrub of the genus Myrica of Myricaceae, with luxuriant branches and leaves, round crown, solitary planting, cluster planting in the lawn, courtyard or roadside. East China and Hunan, Guangdong, Guangxi, Guizhou and other areas are distributed, let's take a look at how to plant bayberry seeds!

Nursery selection

When selecting nursery land, attention should be paid to the location, topography and direction of nursery land. It is best to choose areas with convenient transportation and flat terrain, such as the general slope of the slope is not more than 5 °, and the slope direction is north or northeast as far as possible. The sandy loam with rich soil, loose texture and deep soil layer is better. If the soil is too loose, the upper layer is easy to dry, the lower layer is full of fertilizer and water, the root system extends downward, forming a thick and straight root system, the whisker root is not developed, and clay and saline-alkali soil are not suitable for raising seedlings.

Seed collection

Red bayberry seeds should collect fully ripe fruits from robust adult trees. When collecting seeds, check whether the kernels of the fruits are full or not, and select the fruit trees with abundant kernels for collection. The harvested fruit should choose the appropriate place where the sunlight is not direct, spread out and accumulate the fruit, and the accumulation height generally does not exceed 15 cm. After 4-5 days of accumulation, the pulp is rotten, which can be washed in running water, and the floating gravure is removed to dry the surface for use.

Soil preparation and fertilization

Bayberry seeds should be prepared before sowing. The paddy field or flat land should be ploughed 23 to 27 centimeters deep, and the mountain or deep soil should be ploughed deeper. Sun-white after ploughing, and then layer-by-layer fertilization, repeated ploughing and harrowing, so that the soil is fully fine. The width of the border is 1 meter, the width of the ditch is 30 centimeters, the height of the mountain border is 10-15 centimeters, and the height of the flat border is 20-30 centimeters. Per mu of pig, cattle manure or compost 30005000kg, calcium superphosphate 1520kg, a number of plant ash. Deep drainage ditches should be dug around the paddy fields, and attention should be paid to drought and flood control in mountainous areas.

Sowing method

The red bayberry seeds were soaked in 0.1% potassium permanganate solution or 40% methyl thiophanate 800 times solution for 10 minutes before sowing. After breaking the surface of the nursery border, the seeds were evenly scattered on the surface of the border, with 1.25-1.5 kg per square meter. After sowing, the seeds were gently pressed into the soil with a plank, which was covered with a layer of fine soil, about 2-3 cm deep, and then covered with a thin layer of grass to prevent Rain Water from scouring and the topsoil from drying.

Seedling stage management

When the weather turns cold in the middle of December, the red bayberry seeds should be covered with a small film arch to keep warm. It is necessary to maintain a certain temperature, pay attention to drainage and prevent rodent damage. Generally, the seeds are sown in the middle and late October, the seeds germinate in January of the second year, and the seedlings emerge from the ground in the middle of February. After emergence, if the sun is too strong at noon, it is necessary to open the film ventilation at both ends of the small arch shed to reduce the temperature and humidity in the shed and prevent sunburn or quenching disease, which can be transplanted in late July.

Seedling transplanting

Red bayberry seedlings can be transplanted when they reach about 10 cm high and grow 4-5 leaves. Soil preparation and fertilization should be carried out in the nursery before transplanting. At the same time, 25 kg of lime should be applied on each mu of border or 600 times of topzine should be sprayed. Then, the seedlings were transplanted according to the specifications of row spacing 30 cm 35 cm and plant spacing 8 cm 10 cm. When transplanting seedlings, we should choose the morning and evening of cloudy or sunny days, and irrigate enough fixed root water, transplanting 1.2 ~ 14000 plants per mu.

Transplanting management

Red bayberry seedlings are very sensitive to fertilizer, and even a small amount of thin fertilizer can easily cause seedling death. it is necessary to wait for the root system to grow well and grow 4-5 new leaves before using diluted human feces and urine (1 load of water plus 2 tablespoons of human feces and urine, 0.25 kg of urea). After that, 2% ternary compound fertilizer or rare human feces and urine were irrigated once every half a month, and thin fertilizer was applied frequently to promote the growth of seedlings. Attention should be paid to preventing anthracnose, blight, diseases and insect pests of seedlings. It is necessary to loosen the soil and weed frequently to prevent soil consolidation and weeds from competing with seedlings for nutrients.
