花椒是芸香科、花椒属落叶小乔木,高可达7米;茎干上的刺,枝有短刺,当年生枝被短柔毛。叶轴常有甚狭窄的叶翼;小叶对生,卵形,椭圆形,稀披针形,叶缘有细裂齿,齿缝有油点。叶背被柔毛,叶背干有红褐色斑纹。花序顶生或生于侧枝之顶,花被片黄绿色,形状及大小大致相同;花柱斜向背弯。果紫红色,散生微凸起的油点,花期4-5月,果期8-9月或10月。

花椒树覆盖黑色地膜效果怎么样?花椒树覆盖地膜主要是解决人工除草难的问题。花椒树虽然耐瘠薄,耐杂草侵袭,在杂草中生长也能取的一定的产量,但是要想获得更多的丰收,更高的产量,更高的品质,消灭杂草的危害就是花椒树管理中的一项重要任务。 


过去消灭花椒树杂草全靠人工除草,要耗费农民的许多精力。现在好了,防治杂草有药物防治和铺膜抑制杂草。

除草剂防治虽然效果好,但是保温保墒不如铺膜好,所以人们选择较多的还是铺膜防治。

铺膜主要有两种白色地膜和黑色地膜。白色地膜保温保墒效果好,但是抑制杂草的作用远不如黑色地膜好。万物生长靠太阳。杂草是需要有阳光照射才能发芽生长,黑色地膜透光性很差,正是黑色地膜隔断了阳光的照射,杂草才不能在膜下正常生长,所以有效的阻止了杂草的生长。这就是椒农喜欢铺黑色地膜防治杂草的原因。黑色地膜保温效果比白色的差,但保湿效果也是可以的。在夏天还可以降低地温的作用。

如果你想偷懒人消停,选择黑色地膜防治杂草就是不错的选择。但是效果好,是需要金钱来换取的。铺黑色地膜于人工防治费用相比较还是铺地膜费用小。保护的好可以使用二年没问题的。 

综上所述,花椒树铺黑色地膜一次投资,可多次使用。效果好,人消停。是花椒树保温保湿防治杂草的一种有效的好办法。

回答2:

花椒树覆盖黑地布效果还可以,可以抑制杂草的生长,防止杂草与花椒树争取营养物质,而且保湿效果也还可以,就是保温效果不如白色地布好。

回答3:

花椒树覆盖黑地布效果是不好的,因为花椒本身是需要吸收一定的阳光才能够去生长的,如果盖上黑地布的话就阻挡住了阳光。

回答4:

效果还是非常不错的,这样可以起到保温的作用,能够增加产量。
