摘要
合理施用钙肥是提高蜜橘品质和产量的关键栽培措施之一。通过2 a的田间试验,比较了不施钙肥(CK)、施石灰(L)和施贝壳粉(S)对蜜橘品质和产量的影响。结果表明:与CK相比,L和S处理下蜜橘的含糖度分别提高了13.33%~19.80%和18.10%~26.73%,含钙量分别提高了7.70%~7.76%和10.82%~10.88%,产量分别增加了4.91%~23.99%和9.56%~27.47%。虽然S处理下蜜橘的品质和产量略高于L处理,但增幅均不显著(P>0.05)。相关分析表明,蜜橘的含钙量与产量和经济产值存在密切关系(P<0.01)。因此,在红壤中施用贝壳源钙肥可增加蜜橘的含钙量,进而显著提高蜜橘的产量和产值。
In the cultivation of tangerine(Citrus reticulata),a reasonable application of calcium fertilizer is one of the key measures to improve the quality and yield of tangerine.A two-consecutive-year field experiment was conducted to compare the effects of non-calcium fertilizer(CK),lime(L)and shell-source calcium fertilizer(S)on quality and yield of tangerine.The results showed that:compared with CK,L and S treatments increased sugar content of the tangerine fruits by 13.33%-19.80%and 18.10%-26.73%,increased calcium content by 7.70%-7.76%and 10.82%-10.88%,respectively.At the same time,the fruit yield of tangerine in L and S treatments increased by 4.91%-23.99%and 9.56%-27.47%,respectively.There was no significant difference(P>0.05)between L and S treatments,although the quality and yield of S treatment were slightly higher than those of L treatment.The correlation analysis suggested that calcium content of tangerine was closely related to the yield and profit(P<0.01).Shell-source calcium fertilizer promoted the improvement of tangerine quality and yield.Therefore,applying more calcium fertilizer on red soil will increase calcium content of tangerine fruit,significantly increase the yield and profits of tangerine.
