Background
Yunnan pine (Pinus Yunnanensis) is an evergreen arbor of Pinus of Pinaceae, has strong adaptability to the environment, and is a pioneer tree species for afforestation of barren mountains. The age difference of loosening and maturing in Yunnan is large, generally, natural forests mostly mature in 8-10 years, artificial forests usually bloom and mature after being planted for 5-6 years, reproductive physiology in the first three years is not mature, and hormones for promoting blooming in trees do not reach a certain concentration and cannot bloom and mature. The age of the unraveled flowers and the fructification in Yunnan is related to the origin, the seed source and the site condition of the forest stand and the inheritance of the mother tree. The artificially cultivated Yunnan pine forest is characterized by utilizing seed collection and pollen pini collection to blossom and fruit in advance.

All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Example 1
A method for promoting Yunnan pine to bloom and fruit in advance comprises the following steps:
s1, selecting seedlings
Selecting fine Yunnan pine seeds to cultivate 2-year-old container seedlings;
s2, planting mode
Planting seedlings, namely planting the seedlings on the red soil suitable for the growth of the Yunnan pine;
s3, planting density
The planting density is 2m of row spacing of plants or 2 rows of 1m of row spacing of plants, and the spacing is 2m.
Land preparation and pond digging are needed before transplanting: soil preparation is carried out in a hole shape, and the soil preparation specification is 40cm multiplied by 30cm.
And (3) applying a base fertilizer after digging the pond, wherein the base fertilizer is a compound fertilizer and is 200g of the compound fertilizer per pond, applying the base fertilizer, covering soil for about 5cm, and then planting seedlings. Topdressing 200 g/pond in the first year after planting and the second year after planting, wherein the topdressing is a compound fertilizer. Weeding is carried out once every year in the current year of transplanting, the first year after transplanting and the second year after planting. The pesticide spraying is realized in the way that 25mL of spirotetramat and 15kg of fine mist mixed with 15mI of high-gold are sprayed with water instead of dripping every year in the first year and the second year after planting, so that the harm of livestock is prevented. The high gold used in this example is an insecticide and has a strong penetrating power.
Example 2
A method for promoting Yunnan pine to bloom and fruit in advance comprises the following steps:
1. selecting improved Yunnan pine seeds to cultivate container seedlings of 2 years, and planting the container seedlings on the red soil suitable for the Yunnan pine to grow.
2. The planting technology comprises the following steps:
seed source: yunnan pine (good seed)
Planting seedlings: 2 year old container seedling
Planting time: supplement planting in 7 months in 2018 and 7 months in 2019
Planting mode: planting seedling
Land preparation mode (pond making): hole soil preparation is adopted, and the soil preparation specification is 40cm multiplied by 30cm.
Base fertilizer: and (3) applying base fertilizer for 200g of compound fertilizer per pond, covering soil for about 5cm, and then planting seedlings.
Management measures are as follows: and (4) topdressing at the later stage, wherein 200g of topdressing is carried out in 2019 and 2020, and the topdressing is a compound fertilizer. Weeding is carried out in 2018, 2019, 2020, and 1 time per year. In 2019 years and 2020 years, 25mL of spirotetramat and 15kg of high-gold 15mI water are added into the fine mist to spray the water but not drop every year. Preventing the harm of livestock and the like.
3. Planting method
A wide-narrow row control test is adopted, so that the trees form competition in the early stage and have boundary effect, the trees are promoted to grow and close quickly and highly, and a fast-growing and high-yield forest construction mode of Yunnan pine forest cutting or burning plots is screened out.
The planting density comprises the following 6:
(1) A1: the row spacing of the plants is 50cm;
(2) A2: the plant row spacing is 1m;
(3) A3: the plant row spacing is 2m;
(4) A4: planting 2 rows with the row spacing of 1m, wherein the spacing is 2m;
(5) A5: planting 3 rows at the row spacing of 1m, and the spacing of 2m;
(6) A6: planting 4 rows at a row spacing of 1m and a spacing of 3m.
4. Flowering and maturing rate effect
As shown in figure 1, the Yunnan pine weaved by Jinzheng and Pengze shows that the Yunnan pine needs more than 6 years for flowering and fructification, the flowering and fructification rate of the Yunnan pine in the sixth year is only 0.8 percent, and the flowering and fructification rate is 21.3 percent even in the tenth year.
By adopting the measures adopted by the invention, the planting is carried out in 2018, the phenomenon of blossoming and fructification does not occur in 2020, but the blossoming and fructification rate is over 53 percent in 2021 and 3 months, the time from the planting to the blossoming and the fructification is only 2 years and 8 months, and the time for blossoming and fructification is greatly shortened.

Figure BDA0003824481320000051
Figure BDA0003824481320000061
According to test and determination data, the influence of different densities on growth, flowering and fructification is obvious, the density of the Yunnan pine planted in the plant row spacing of 50cm is too large, the Yunnan pine grows slowly and flowers are relatively less, and the flowering and fructification rate of the Yunnan pine weaved by Jinzheng Zhou and Pengzhan is greatly improved compared with the flowering and fructification rate of the Yunnan pine weaved by Jinzheng Zhou and Pengzhan.
The method promotes the Yunnan pine pollen to bloom earlier by adopting a planting method and a management measure different from the prior art, provides a good technical measure for utilizing the pine pollen, particularly provides a good technical measure for the collection of the pine pollen, blooms earlier, most trees are less than 2 meters, and provides a good technical measure for cultivating a dwarf Yunnan pine pollen collection garden.
