摘要
为了探索雷竹笋早出丰产栽培技术,在湖北崇阳低山丘陵区分别进行了不同覆盖物、不同覆盖厚度、不同覆盖时间覆盖雷竹林的试验,研究覆盖对雷竹笋出笋的影响。结果表明,以谷壳和稻草(2︰1)混合使用作为覆盖物的经济效益最高,提早笋期53 d,早期笋产量占58.5%,利润5.96元/m2。覆盖厚度以30 cm左右为好,提早笋期56 d,早期笋产量占69.1%,当年效益高,可留母竹多。覆盖最佳时间为11月下旬,提早笋期62 d,早期笋产量占77%。该套覆盖技术具有明显的提早出笋和增产效果。
In order to explore cultivation techniques of early sprouting and high yield ofPhyllostachys praecox, mulching cultivation of different cover thickness and time was tested by different mulches at low mountain and hilly areas of Chongyang, effects of mulching on bamboo shoot sprouting in P praecox were researched. The results show that the treatment of husk of rice and straw （2 ： 1） as mulch has the highest economic benefit, bamboo shoots sprout 53 days early, early bamboo shoot yield is 58.5%, and profit is 5.96 Yuan/m2. The optimum cover thickness is about 30 cm, bamboo shoots sprout 56 days early, there is higher benefit in the same year, and more female bamboo may be kept. The optimum time is late November, bamboo shoots sprout 62 days, and early bamboo shoot yield account for 77%. The set of mulching cultivation techniques have significant effects on early sprouting and increasing yield.
