A PRIMARY REPORT OF DIFFERENT PLANTING DENSITIES TEST OF CITRUS TANGERIAN FOR EARLY-BEARING AND HIGH-YIELDING

  • Publish Date: 1986-09-15
  • In growing Citrus tangerina, the different planting densities under different natural and cultural conditions showed that a density of 100 to 212 trees per mu got a remarkable result of stable, high-yield and better economic benefit as compared with those conventional densities (48-66 trees per mu).The densely planted trees began to bear fruits in the second year.In the successi e 5 years (1981-1985), on an average, in comparison with conventional density of 66 trees/mu and 48 trees/mu, the yield of 100 trees/mu was increased of 645.4 Kg and 885.0 Kg respectively, and its profit was also increased RMB $97.3 (+19%) and 247.5 (+71%) respectively. while the yield of 212 trees/mu was increased 542.0 Kg and 657.3 Kg respectively, and its profit was increasad RMB $237.5 (+48%) and 387.6 (+111%) respectively.Technical requirements: It is preferable to graft Citrus tangerina on C.trifoliate root stock with a stem over 0.8cm in diameter and well developed root system, and to culture carefully to be short-trunk, multi-branches, vigorous tree, it so as to get more than 20 of the primary, secondary and tertiary shoots in the grafting year. After planting, it is importan to practise "forcing-and-controling" cultu c technique in accordance with the features of fruit bearing at various stages, with an aim to control the summer shorts and culture the autumnt ones, to achieve early-bearing and limit the crown extension, meanwhile timely thinning out according to the planting densiy is very important to induce high yield and best quality.
