柞蚕饲料树种的优劣,是养小蚕保苗增产的一个关键问题。通过多年保苗场的实际种植和养小蚕以及对树种的物候生长、叶质分析、资源分布等调查,已评选出养小蚕价值较高,易于繁殖栽培,生长较快,资源丰富,适应地区广的蒿柳(Salix viminalis Linn)、麻栎(Quercus acutissima Carr)、辽东栎(Q.Liaot-ungensis Koidz)、蒙古栎(Q.mongolica Fisch)等树种。一、方法选用麻栎、辽东栎、蒙古栎、蒿柳、山荆子(Malus baccata Borkh)等柞蚕饲料树种,通过多年种植,观察生长情况,调查枝叶生长量;多年的保苗场春、秋养小蚕试验,调查保
Advantages and disadvantages of tussah feed tree species, raising small silkworm seedlings to increase production of a key issue. Through years of actual planting and raising silkworm rearing hatchlings and phenological growth of trees, leaf quality analysis, resource distribution survey, has been selected to raise young silkworm value is high, easy to reproduce, grow fast, rich in resources, adapt to the region Salix viminalis Linn, Quercus acutissima Carr, Q.Liaot-ungensis Koidz and Q. mongolica Fisch. First, the method selected Quercus acutissima, Quercus liaotungensis, Quercus mongolica, Artemisia annua, Malus baccata Borkh and other tussah feed tree species, through years of planting, observation of growth, to investigate the growth of branches and leaves; Small silkworm test, investigation insurance
