滇é‡æ¥¼ is a perennial herb with obvious post-ripening effects. The embryo needs to be matured after germination, and the emergence rate is low. The second-stage planting technique of one-leaf to four-leaf seeds of the heavy-duty seed can minimize the fatal effect of transplanting on the growth of the squat building and shorten the artificial planting cycle of the entire squat building. The technology is now described as follows.
1. In the area with an altitude of 1600-3100m, the annual average temperature is 12-13 degrees, the frost-free period is more than 270 days, the annual rainfall is 850-1200mm, the rainfall is concentrated in June-September, and the air humidity is above 75%. It is the place for the night tide.
2. Set up a awning on the night tide soil, apply organic fertilizer, plow the night tide soil 25cm, and then make a seedling bed of 1.2m wide × 20cm height; the drainage ditch between the seedbed is 0.3m wide and 0.2m deep; The shed wood piles are piled at 4×4 pitch, and the height of the top of the pile is 2.2m from the ground; 2000kg of organic fertilizer is applied per acre.
3. After the seeds are germinated, the seeds are planted on the night sown soil with awnings. The shading net has a shading rate of 70% in the first year of cultivation and a shading rate of 60% in the second year. The shading rate is 50% from the beginning of the third year of cultivation.
4. Select the place where the soil is loose and fertile, and the irrigation and drainage is convenient. The planting land is adjusted to have a slope of 10 degrees. The length of the slope is north and south, the width direction is east and west, the width of the slope is 1.2m, and the width of the groove is 20cm. When the whole land is prepared, 2000 kg of fully decomposed farmyard manure, 20 kg of superphosphate and 20 kg of potassium sulfate are applied as base fertilizer.
5. When the seed is seeded from 1 leaf to 4 leaves in step 3, transplanted from the seedbed to the stalk in step 4, the seedling depth is 3 cm. After transplanting, in May of each year, 1500 kg of organic nitrogen solution with a nitrogen content of 0.6% per mu is used to trace the roots; in July, 1000 kg of farmyard manure, 8 kg of phosphorus superphosphate, and 5 g of potassium sulfate are applied per mu. After the partial cropping of the ground in November, the farmer's fertilizer was applied to 2000kg.
6. The transplanting time is from March to April, and the underground stems of the disease-free and normal form are cut into 2 sections, and the pine leaves after 1cm are covered after transplanting.
