一、林粮间作模式及效益整地:挖坑或开沟长宽各1m、深0.8m,每棵树施基肥25kg、磷肥1kg、碳铵0.5kg与土混匀,植树时回填坑(沟)内。植树:株行距1.5×10m,每hm~2660棵,选择胸径3cm以上大苗,深栽60—70cm,栽后浇透水。追肥:第二年开始。于每年春季结合浇地和夏季7—8月份结合降雨追肥2—3次,2—4年每树每次追尿素0.25—0.5kg,5—8年每树每次追尿素0.5—1kg。营林:第三年秋后间伐,隔株去株伐330棵,剩330棵,株行距变为3×10m。第五年秋后间伐,隔株去株伐165棵,剩165棵,株行距变为6×10m。第八年皆伐。
First, intercropping modes and benefits of forestry Land preparation: digging or ditching the width and width of the 1m, 0.8m deep, each tree 25kg base fertilizer, phosphate fertilizer 1kg, ammonium bicarbonate and soil mix 0.5kg, backfill pit (ditch) Inside. Planting trees: spacing of 1.5 × 10m, each hm ~ 2660, choose more than 3cm diameter seedlings, planting 60-70cm, transplanting water. Top dressing: the second year begins. In combination with irrigating spring every July and July and August with 2-3 times of rainfall top dressing, 2 to 4 years, each tree reclaimed urea 0.25-0.5kg, 5-8 years of each tree to recover urea 0.5-1kg. Silviculture: In the third year of autumn, the interval thinning was carried out. 330 plants were planted and 330 plants were left. The row spacing changed to 3 × 10 m. The fifth year of autumn thinning, every strain to plant 165 trees, leaving 165, row spacing into 6 × 10m. Eighth year are cutting.
