以豫北新建茶园土壤为材料,通过对耕层土壤(20 cm和40 cm处)p H值的检测,研究了茶苗移栽前施“硫磺粉+草炭”和移栽后施“菇渣”、作物间作(花生或三叶草)或补施“硫磺粉+草炭”对茶园土壤p H值的影响。研究结果表明,移栽前施“硫磺粉+草炭”可以显著的降低土壤p H值,土壤由中性或弱碱性降低为20 cm处平均p H=6.18和40 cm处平均p H=6.57;移栽后铺施“菇渣”或间作花生对土壤p H进一步降低并未见显著的影响,而补施“硫磺粉+草炭”或间作绿肥(三叶草)对进一步降低土壤p H作用显著。
Based on the p H value of topsoil (20 cm and 40 cm) in tea plantations in northern Henan Province, the effects of applying “sulfur powder + peat” and transplanting before transplanting were studied. “Mud residue”, crop intercropping (peanut or clover) or supplemental “sulfur powder + peat” on soil p H value in tea plantation. The results showed that the application of “sulfur powder + peat” before transplanting significantly reduced the soil p H, and the average soil p H reduced from neutral or weakly alkalized to 20 cm. Mean p H = 6.18 and average p H at 40 cm = 6.57. There was no significant effect on the soil p H after transplanting and applying “mushroom residue” or intercropping peanut, while the supplementation of “sulfur powder + peat” or intercropping green manure (clover) further decreased Soil p H significant effect.
