雷竹因早期打雷即出笋而得名雷笋。雷笋具有品质优良、发笋早、产量高等特点。通过覆盖促成栽培提早发笋,使春笋冬出,填补了冬季春笋空白,能取得良好的经济效益。 雷竹覆盖提早发笋主要机理在于:①雷竹自然发笋期早。竹林发笋时期取决于该竹种发笋对温度(主要是地温)的需求。雷竹笋发笋起始温度为8℃;通常,土温在连续8℃条件下,积温(若干时间的温度累积值)达到200～250℃时,竹笋萌发出土。②林地覆盖增温。通过
Thunder bamboo shoots because of the early thunder that is named bamboo shoots. Thunder bamboo shoots with high quality, early shoots, high yield characteristics. Promote the cultivation through the coverage of early bamboo shoots, so that the spring bamboo shoots out of winter to fill gaps in winter, can achieve good economic returns. Phyllostachys bamboo shoot early coverage of the main mechanism is: ① natural shoot bamboo shoots early. The bamboo shoot period depends on the bamboo shoots on the temperature (mainly ground temperature) needs. Bamboo shoots shoots bamboo shoots starting temperature is 8 ℃; usually, soil temperature in continuous 8 ℃ conditions, accumulated temperature (a number of time the temperature accumulated value) reached 200 ~ 250 ℃, the bamboo shoots germinated. ② forest cover warming. by
