It is believed to be familiar that it is a common tree species in rural areas, gardens and cities, originating in china, that is resilient to land while absorbing harmful gases such as sulphur dioxide and hydrogen chloride. In terms of technology and management, some farmers are not yet mastered, resulting in poor quality and production of seedlings in the country, with considerable losses. The following is a presentation of the key techniques used in the cultivation of the country's herds, so that they can be mastered。
National planting methods
First, before seeding, the importance of the soil and environmental choices that are cultivated requires that the terrain be flat, fertile and deep, and that no seeding be allowed in arid, infertile, and incubated nurseries; and secondly, the treatment of seeds is also important, and preplanting is recommended for either leaching or sandy treatment。
A description of the leaching method: insulated with 80°c hot water, using tools to mix water until water is at 45°c, it is necessary to bubble the seeds one day, to see the seeds expand, to take the seeds out, and to cover the seed with wet cloths, and to emphasize that if the seeds do not swell, they need to be repeated by the above steps until they swell, so that they can be planted in a moving state。
Sushifa describes the fact that about 12 days before the seed is planted in the sand, it is necessary to soak the seed in water for 24 hours, then put the seed into the sand after 24 hours, using tools such as a plastic basin, where the seed size is one third of the soil, evenly mixed, covered with plastic sheeting, to roll the pine land once a day, and then sow the seed once a day
