After the thinning and reconstruction of the parent forest, the forest canopy density suddenly decreased, the woodland was exposed, and weeds were prone to breeding(2 gallon nursery pots wholesale). Weeding and loosening should be carried out. The key technology for the reconstruction of the mother forest is thinning, which can improve the conditions of light, water, fertilizer and sanitation(2 gallon pots wholesale), promote the growth and development of the mother tree, and improve the seed yield and quality.

(high quality 9 inch plastic plant pot suppliers canada)For dioecious tree species, attention should be paid to maintain an appropriate ratio between male and female, and make male plants evenly distributed to facilitate powder(14 gallon nursery pots wholesale). There are many kinds of seed orchards, which can be classified according to the propagation method and the degree of improvement: according to the propagation method(plastic bonsai pots wholesale), they are divided into clone seed orchards and seed seedling seed orchards.

For those who are inferior to the best stands, the age of harvesting trees should be more than 100 years(15 cell propagation trays wholesale). Before harvesting, dozens of excellent trees are selected from such stands, and the seedlings are planted in the seed year and planted in groups. The seeds are also built by clones or families of the selected superior trees(4.92inch plastic plant pots). The plantation is for the purpose of producing seeds with high genetic and planting qualities. To increase the seed yield per unit area.

The forest needs to be isolated and intensively managed from the outside pollen to ensure the seed quality High-quality, high-yield and stable production(21 cell propagation trays wholesale). The seed garden is called improved seed garden. The seed orchard should be established in the center of the seed supply area to facilitate seed harvest, distribution and allocation(2.5 inch square plastic pots).

The former is based on the results of progeny measurements. It was built after scouring poor clones from the primary seed orchard. The latter is to rebuild the garden with excellent clones of progeny. The seed supply range of each seed orchard has a certain regional limit(bulk buy plastic plant pots). Only by using the improved seeds in the appropriate area can the maximum yield potential be obtained.

Clonal seed orchards are seed orchards established by grafting or inserting the branches of superior trees, and are the main forms of current seed orchards(98 cell propagation trays wholesale). The size of the seed orchard should be determined according to the afforestation plan and seed requirements in the supply area, as well as the prediction of the yield per unit area of the seed orchard(4 inch plastic pots bulk), and leave some room for further development and adjustment of the seed orchard.
