Technique for planting sarcandra glabra by use of vacancy area of eucalyptus forest

Abstract

The invention relates o a technique for planting sarcandra glabra by use of a vacancy area of a eucalyptus forest and specifically relates to a technique of guaranteeing that the survival rate of the sarcandra glabra in the eucalyptus forest is above 90% and the biological yield of the sarcandra glabra can be increased. The technique is characterized in that the vacancy area of the eucalyptus forest is plowed and harrowed by the depth of 15-20cm, and the plowed and harrowed soil is covered with an agricultural film which is 60cm wide and 0.06mm thick after raining; a plant growth regulator and a nutrient solution are sprayed on the foliage so as to be absorbed and utilized favorably, and then the ability of the sarcandra glabra resisting the adverse situations caused by large water absorption and fertilizer absorption quantities of the eucalyptuses is enhanced. The water in the rainy seasons can be stored and the soil can be improved, the water and the soil can be conserved and the growth environment of sarcandra glabra planting can be improved, and the transplanting survival rate of the sarcandra glabra can be increased and the growth of the sarcandra glabra can be promoted. The plant growth regulator and the nutrient solution are directly sprayed on the foliage of the sarcandra glabra and can be absorbed by the sarcandra glabra favorably, and therefore, the water absorption and fertilizer absorption competitiveness of the sarcandra glabra is enhanced and the adverse situations of drought and fertilizer deficiency due to large water absorption and fertilizer absorption quantities of the eucalyptuses.

Description

a technical field [0001] The invention relates to a method for interplanting eucalyptus forest medicines, in particular to a technique for planting Chinese herbal medicinal herb coral by using open spaces under eucalyptus forests, and belongs to the field of forestry science. Two background technology [0002] Eucalyptus belongs to the Myrtaceae (Myrtaceae) genus Eucalyptus. It is one of the three world-renowned fast-growing tree species and an important pillar of Guangxi's modern agriculture. effect. Eucalyptus grows extremely fast, has a short rotation period, mature technology, few pests and diseases, and good economic benefits, so the promotion speed in Guangxi is very fast. However, eucalyptus requires a lot of water and fertilizer. During the promotion of eucalyptus, there are some problems such as sparse understory vegetation and reduced biodiversity. Therefore, it is particularly important to study different eucalyptus planting and management models and to promote ...
