The invention discloses a special
fertilizer for excentrodendron hsienmu and a preparation method of the special
fertilizer. The special
fertilizer is prepared by adopting the following components in parts by weight: 30 to 45 parts of mulberry
branch powder, 15 to 25 parts of sugarcane
tail, 20 to 25 parts of pond
sludge, 10 to 15 parts of
compost, 3 to 5 parts of
perlite, 2 to 3 parts of
chitosan, 3 to 5 parts of
zinc sulfate, 1 to 2 parts of
manganese sulfate, 0.5 to 1 part of
borax, 0.5 to 1 part of
ammonium molybdate, 1 to 3 parts of fertilizer activating agent, 2 to 3 parts of injurious
insect repellent and 1 to 2 parts of zymophyte. The
compost is formed by mixing and composting 30 to 50 parts by weight of cattle
manure, 10 to 15 parts by weight of
chicken manure and 3 to 5 parts by weight of
straw ash for 3 months or more, the
compost is overturned once a month, and 0.5 to 1 part by weight of pulverized
lime is added while the compost is overturned. By adopting the special fertilizer, the
nutrition of the excentrodendron hsienmu during the growth process can be supplemented in time, the content of organic matters in soil also can be increased, the soil environment can be improved, an injurious
insect repelling effect also can be realized, the excentrodendron hsienmu grows well after being fertilized, the wood texture is hard, the yield is increased by 15 percent or more, and the economic benefit and social benefit are greatly increased.
