1、春季繁殖水葫芦大量增殖的适宜温度是20—30℃。温度过高,会造成种苗徒长,植株生长脆弱,不易直立,抗逆性差,不利放养;过低,不能大量分株。一般是在4月上旬就于自然沟塘搭盖塑料薄膜棚,在棚内做成苗池,池底铺3—4寸厚的沙塘泥,每平方米施3—5斤优质腐熟厩肥,与塘泥混拌均匀,保持半尺水层,然后将水葫芦密集均匀地放入水中。防止与绿萍混养,以免与水葫芦争光,争肥,争气,影响生长。在分株前不要随意挪动种苗,以免影响扎根。在春繁期严防高温出现,注意通风降温管理。在夜间气温达10℃以上
1, Spring breeding water hyacinth suitable for large-scale proliferation is 20-30 ℃. When the temperature is too high, it will cause the plant seedlings to grow long and the plant growth will be fragile and difficult to erect. The resistance will be poor and unfavorable stocking will occur. Usually in early April on the natural ditch pond covered plastic film shed, made in the shed Miao pool, pool bottom shop 3-4 inch thick sand mud, 3-5 kg per square meter of high-quality decomposed manure, Mix well with pond mud, keep half a foot of water layer, and then put water hyacinth densely and uniformly into the water. Prevent polyculture with ophthalmology, lest competing with water hyacinth, fight fat, fight, affect growth. In the ramets do not move the seedlings, so as not to affect the rooted. In the spring to prevent high temperatures appear, pay attention to ventilation and cooling management. Temperatures above 10 ℃ at night
