油桐是我国特有的木本油料树种之一,栽培历史已有一千二百多年.桐油是我国传统的出口商品,在国际市场上享有崇高的声誉.我省人口稠密,土地珍贵,桐林面积不大,近年来油桐面积还有下降的趋势,这就使得桐油非常紧缺的状况变得更为突出.为改变桐油供需矛盾,如进行大面积成片种植尚有一定的困难.因此,号召有条件的农户,利用家前屋后,四旁荒地荒滩种植油桐树,解决自用桐油问题,便是一个主要途径之一.本文调查的是溧水县渔歌乡傅家边村上任庄植桐农户任启斌利用房前屋后栽植的油桐树生长情况.油桐栽植与管理(一)林地概况任启斌房前屋后栽植的油桐地系石头岗地,黄棕沙壤土,土层薄,肥力差.(二)植苗造林栽植前挖成50×50×50厘米的穴,穴内施厩杂肥一担(35—40公斤).苗木为1—2年
Tung tree is one of the unique woody oilseed species in our country, and it has been cultivated for more than 1200 years. Tung oil is a traditional export commodity of our country and enjoys a high reputation in the international market.It is densely populated, precious land, Area is small, there is still a downward trend in the area of tung oil in recent years, which makes tung oil is in a very shortage of conditions become more prominent.To change the tung oil supply and demand conflicts, such as large areas into pieces of planting there are still some difficulties.Therefore, It is one of the main ways to call for qualified peasant households to use the front houses and the abandoned wasteland to grow tarragon trees on their own to solve the problem of their own use of tung oil.This paper investigates Renqin Bin, a farmer from Zhuangdingtong Village, Fu Jiabian Village, Yuge Township, Lishui County, The growth of tung tree planted in front of the house was taken. (1) Plantation and management of tung tree (a) Overview of woodland Ren Qixin The tung oil field planted in front of the house was stone hillock and yellow brown sandy loam with thin soil and poor fertility. ) Planting seedlings planted before planting 50 × 50 × 50 cm hole, hole stubble mixed fertilizer (35-40 kg).
