NOVELTY - Cultivating fructus forsythiae, comprises (i) choosing cultivation land having easy irrigation facility, flat surface, rich in organic substance, non-alkaline fertile sandy soil, and pH of 6-7, and weeding, and plowing; (ii) processing seeds; (iii) planting the seedlings; (iv) carrying out field management; (v) carrying out growth stage; (vi) preparing fertilizer; (vii) promoting branching of 4-5 weeks old grown plant, and carrying out second-stage branching of plant; and (viii) hydrating once in every 1-2 weeks based on soil conditions, and cultivating based on timely basis, and weeding.    USE - The method is useful for cultivating fructus forsythiae (claimed).    ADVANTAGE - The method shortens seed germination time, temperature, humidity and seeding depth; produces leaves which are slightly rotten, and pests-free; utilizes nutrient fertilizer; promotes air permeability into soil having improved structure; increases soil fertility; inhibits the growth of weeds, and thus it reduces weeding cost; reduces loss of soil, and fertilizer; and is environmental friendly.    DETAILED DESCRIPTION - Cultivating fructus forsythiae, comprises (i) choosing cultivation land having easy irrigation facility, flat surface, rich in organic substance, non-alkaline fertile sandy soil, and pH of 6-7, and weeding, and plowing the land up to cultivation depth of 25-30 cm; (ii) processing seeds by soaking large plump grain seeds in warm water for 15 hours at 55-60 degrees C, to obtain submersible seed; (iii) planting the seedlings in a row at spacing distance of 35-40 cm, planting depth of 1-1.5 cm, and then covering soil up to a thickness of 0.3-0.5 cm, and sowing up to a density of 5-6 plants/m2; (iv) carrying out field management by controlling the temperature at 17-25 degrees C, and air relative humidity at 65-75%; (v) carrying out growth stage by maintaining preemergence effect, and soil moist under good conditions, and hydrating so as not to affect the unearthed soil compaction; (vi) preparing fertilizer by crushing 60-90 g dendrimeric carboxymethyl (CM) starch, 50-60 g seaweed, 1-2 kg wheat straw and 500 g chicken manure, and completely mixing, adding to the land after postemergence, and hydrating to promote root development deep into the soil; (vii) taking out leaves of 7-9 cm height having 6 or more blades, retaining the lower part of 3-4 leaves, and promoting first-stage branching of 4-5 weeks old grown plant, and carrying out second-stage branching of plant, and taking out lateral branches, and maintaining the lateral branches-containing less than 4 leaves; and (viii) hydrating once in every 1-2 weeks based on soil conditions, and cultivating based on timely basis while hydrating each time, and weeding.
