平地密植板栗园幼树期间作试验

Experiment on Different Intercropping Crops in Sapling Stage of Close Planting Chestunt orchard in Flat Land

当前板栗建园主要采用栽植2a实生大苗,第3年春季进行优种嫁接的方法。为了解决板栗建园初期经济效益低的问题,于2016~2019年连续4a进行了平地密植板栗园幼树期间作不同作物试验。结果表明:板栗建园前3a间作花生,第4年间作耐阴的旱稻子或谷子,间作试验园年均纯收入可达22334.3元/hm2以上,可显著提高栗园早期经济效益。

At p resent,the mainly way of Chinese chestnut orchard construction is firstly planting two-year-old seedlings,then grafting chestnut cultivars in the spring of the third year.In order to solve the problem of low economic benefit in the early stage of chestnut orchard,the young chestnut/crop intercropping cultivation experiments were carried out in Zhangnanwa village,Baozidian town,Zunhua city,Hebei province for four consecutive years from2016 to 2019.The results showed that the early economic benefits can be significantly improved with an annual net income of more than 25439.2 yuan per hectare when the peanuts were planted as inter-row crops in the first three years,and the shade-tolerant crops such as rice,millet were intercropped in the fourth year.
