In order to maintain the health and vigour and to sustain the productivity, a pruning experiment was conducted on four year old "Balwant" cultivar of aonla grown in laterite soil, planted at a spacing of 5m×5m. To find out the best pruning method, six levels of pruning was performed i.e., (1) Light judicious pruning, (2) Detopping of primary branches at 8 feet from ground level + removal of all secondary branches, (3) Detopping of primary branches at 8 feet from the ground level + removal of all secondary branches at 2 feet from the base of primary branches, (4) Detopping of primary branches at 8 feet from the ground level + removal of all secondary branches at 1 feet from the base of primary branches, (5) Light judicious pruning + Detopping of plant canopy of at 8 feet from the ground level, (6) No pruning (control). Results of three consecutive years of investigation revealed that light judicious pruning of thin, overlapping, criss-crossed, dead, unproductive and looping branches gave highest fruit yield in all the three years and resulted 64.4 percent yield increment over control when average of three years was considered. Severe pruning of primary and secondary branches caused drastic reduction of yield for two consecutive years after pruning. Judicious pruning helped to produce better sizeable and quality fruits. 展开更多

为使氮磷钾的需要量标准化,提高西孟加拉邦砖红壤地区的腰果产量,1986~1988年在该邦的贾尔格兰姆(Jhargram)地区研究站进行了研究。处理为每年每株单独或混合施氮0,300,600克,磷0,200,400克和钾0,300,600克。植株4年生时(1985年)施全... 为使氮磷钾的需要量标准化,提高西孟加拉邦砖红壤地区的腰果产量,1986~1988年在该邦的贾尔格兰姆(Jhargram)地区研究站进行了研究。处理为每年每株单独或混合施氮0,300,600克,磷0,200,400克和钾0,300,600克。植株4年生时(1985年)施全量肥料。2年的研究结果表明,施最高水平的氮(600克/株·年)显著增加单株坚果数及坚果产量,施较高水平的磷(400克/株)也增产(增加果数及重复),施较低量的钾(300克/株)也增产。只有施氮600克/株·年的处理才显著提高出仁率。 展开更多

作者 s. n. ghosh 潘贤丽 《世界热带农业信息》 1989年第3期24-25,共2页
为寻找优良的和抗安氏锤刺盲蝽的品种,1985—86年在贾尔格兰腰果研究站开展了研究。在1978年收集的17个品种中,有两个品种,即BLA—39—4和TN—16最高产而且受安氏锤刺盲蝽为害率最低,最易受盲蝽为害的品种是NLR—2/1和H—3—17其产量最低。
