Many tree species in the forest are parthenistic flowers(32 cell seedling trays wholesale), such as pines, cypresses, many species in the Cedar family, and many valve-leaf trees (such as birch, probing and walnut, etc.). There are many factors that affect the yield and quality of forest tree seeds, which can be divided into mother tree conditions, soil conditions, climate and weather, and biological factors. Under normal circumstances(3.94inch plastic nursery pots), there are many trees on the fertile, humid, well-drained soil, and the seed quality is also high.

In a warm climate, due to the higher temperature and longer plant growth period, the temperature has an important influence on the flowering and fruiting of the trees(1 gallon nursery pots wholesale). Therefore, through artificial measures to improve the soil and improve soil fertility, to obtain large quantities and high-quality seeds, on the soil with poor fertility roots, forest trees grow slowly, set late and small set, and low quality(nursery tray manufacturers). The amount of soil water content is closely related to the flowering and fruiting of forest trees.
(heavy duty plant trays manufacturers canada)Accumulates nutrients for a long time and accumulates much, so the yield of seeds is high(3 gallon nursery pots wholesale). The best quality. If the temperature is higher than the average temperature over the years, there will be more flowering, and there will be a rich year, on the contrary, there will be less fruiting. In addition, the photoperiod, which is the length of day and night, is very important for the flowering of forest trees(4.33inch plastic plant pots). Wind is good for pollen transmission, but strong wind will cause falling flowers and fruits.
In areas of high degree of magnificence and high altitude(5 gallon nursery pots wholesale), due to the low temperature, it is not conducive to the growth of dried forest trees, and it is also not conducive to the differentiation and formation of flower buds. For stands with small canopy density, the pollination conditions of the forest have a great influence on the yield and quality of seeds(1.5 gallon nursery pots). If it rains continuously during flowering, it will affect the pollination of wind-borne flowers.(heavy duty plant trays manufacturers canada)
Temperature also affects the interval between tree growth(7 gallon nursery pots wholesale). For example, in the warm area, Madong has a large amount of fruiting almost every year, but the further it goes north, the more obvious the interval of fruiting is. Forest trees must have sufficient light(1 gallon plastic nursery pots). The intensity of the light can affect the temperature, the photosynthesis and the accumulation of nutrients, and thus affect the flowering and fruiting and the yield and quality of seeds.
(heavy duty plant trays manufacturers canada)Long-sunshine tree species such as Korean pine, Pinus sylvestris var. Mongolica, and white sticks are suitable for cultivation in high-row areas(10 gallon nursery pots wholesale). If they are in short-sunshine areas, they can grow but cannot bloom. The humidity is too high, not only the temperature is low, but the rain will wash away the pollen(rootmaker propagation trays). In addition, low temperature and rain limit insect activity and make it difficult for insect-carrying flowers, which affects the yield and quality of seeds.
During the flowering and fruit growth, if it is attacked by catastrophic factors such as ice husk, diseases and insect pests, it will seriously affect the yield and quality of seeds(15 gallon nursery pots wholesale). In addition, tree species such as poplar, plum, elm, and shuttle are not particularly prosperous, and seed production is relatively stable in each year(one gallon pot): Masson pine, Cunninghamia lanceolata, Chinese maple, Robinia pseudoacacia and other tree species have short fruiting intervals, generally 1-2 years.
