胡椒,特别是杂交种班尼约尔-1对养分需要量的实验证据还很不足。据Raj(1973)报道,在沙捞越的砂质土上,每年每株施尿素12英两,氯化钾16英两,就能获得最高的经济产量,而在重僵粘土上,最适施肥量为每年每株尿素12英两,双料过磷酸钙8英两和氯化钾16英两。据本文作者估计,单株平均年产干椒1公斤
The experimental evidence of the nutrient requirements of pepper, and especially of the hybrid brethren-1, is still far from adequate. According to Raj (1973), the highest economic yield can be obtained on sand sandy soil in Sarawak at 12 barrels of urea per plant per year and 16 bar of potassium chloride per plant per year. On heavy clay, the optimum amount of fertilizer Each year for each urea 12 British two, double superphosphate 8 British two and 16 British two potassium chloride. According to the author’s estimation, the average annual output of dried peppers is 1 kg per plant
