Medicinal resources and intercropping techniques of Bletilla striata

Intercropping refers to planting more than two kinds of crops in a certain number of rows at the same time, which can not only make full use of the land, but also make full use of light energy and carbon dioxide, and increase crop yield by about 20%. Baiji grows slowly and has a long cultivation life. It can grow corn, green vegetables, radish and other short-term crops or co-growing crops in 1-2 years to increase income [Jishan Huayao].

Intercropping between Bai and Yun Mu Xiang can not only reduce the cost of artificial shade, but also reduce the high cost of artificial weeding, increase crop yield and increase economic income at the same time. Main techniques: ① soil preparation, applying rotten farm manure 30000 ~ 45 000kg/hm2 and nitrogen, phosphorus and potassium compound fertilizer 225~450kg/hm2 as base fertilizer; ② box management, north-south direction, box width 100~120cm, box height 20~25cm, gully width 20~30cm ③ interplanting, planting from March to April, planting Baiji tuber in 30 ~ 50cm in the east, and planting yellowwood seeds in the rest of the land. The row spacing of Baiji is (8 cmX 10) cmX (10-15) cm, trench planting, ditch depth 5-8cm, and soil cover 2-4 cm after placing white and tuber. The planting of Radix Aucklandiae is planted in triangular holes, and the hole spacing is (10 ~ 20) cmX (20 ~ 30) cm. ④ topdressing was applied in May-June of the first year, urea 225-450kg / hm ~ 2 was applied in May-June of the first year, and 300~600kg/hm2, a compound fertilizer containing nitrogen, phosphorus and potassium, was applied in August-September of the first year. The third time, from November to December of the first year, the compartment was covered with mature farm manure 15000kg / 30000kg / hm ~ 2; the fourth time, in June of the second year, the compound fertilizer containing nitrogen, phosphorus and potassium was applied to 300kg / 600kg / hm ~ 2; ⑤ field management, soil cultivation 2-3 times in the second year; ⑥ harvest, and digging of Magnolia officinalis and Baihe in November-December of the second year. In addition, the soil can be covered with plastic film again during the interplanting period, the film can be broken in time after emergence, and all the plastic film can be removed from November to December of the first year when combined with rotten farm manure.
