[目的]获取华南地区黄秋葵高产的最佳刈割高度。[方法]设置刈割高度100、80、60、45、30cm几个处理,以摘叶处理为对照,测定不同刈割高度对黄秋葵茎、叶产量及茎叶比的影响。[结果]黄秋葵叶产量以刈割高度30cm的处理最高,为15622．20kg／hm^2,最低的是刈割高度100cm的处理;茎产量以刈割高度45cm的处理最高,为95550．60kg/hm^2,最低的是摘叶处理;茎叶比以刈割高度100cm的处理最高,为1．49,最低的是刈割高度45cm的处理;总物质产量以刈割高度45cm的处理最高,为79155．60kg／hm^2,摘叶处理的最低。如果种植用于取叶片青饲动物则应取30cm的刈割高度;以黄秋葵的茎叶为材料的饲料加工种植应取45cm的刈割高度。[结论]为黄秋葵生产实践提供了理论依据。  相似文献   

Yield response of okra, Abelmoschus esculentus (L.) Moench to leaf damage by the flea beetle, Podagrica uniforma Jacoby (Coleoptera: Chrysomelidae)     

O.O.R. Pitan  E.E. Ekoja 《Crop Protection》2011,30(10):1346-1350

Yield-related response of okra plants, Abelmoschus esculentus (L.) Moench, to artificial infestation of the flea beetle (Podagrica uniforma Jac.) at different densities (0, 5, 10, 20, 30, and 40 pairs per cage) was studied in screen house and field experiments. In both experiments, increase in beetle density resulted in a significant reduction (P < 0.05) in fruit production, fruit length, fruit width, fresh fruit weight, number of seeds per fruit, 100 seed weight and fresh fruit yield. In addition, higher densities caused more dry matter accumulation in the seeds than in the husk of okra fruits. Compensation was noticed at the 5- and 10-pair levels of infestation in some of the variables measured. Fresh fruit yield reduction was more than 50% when beetle density was increased beyond 20 pairs per cage in both experiments. The lowest density of P. uniforma at which significant reduction (P < 0.05) occurred in fresh fruit yield per cage, when compared with the control, was the 20-pair level, representing the damage threshold of the beetle at which initiation of control measures would be justified. Regression analysis indicated that flea beetle density was linearly associated with fruit damage and fresh fruit yield. Also, chi-square analysis showed that the models derived from the screen house and field experiments were not significantly different (P < 0.05) from each other, and either could be used for prediction purposes.  相似文献   

Influence of Cocoa Pod Husk-Based Compost on Nutrient Uptake of Okra (Abelmoschus esculentus (L.) MOENCH) and soil properties on an Alfisol

This experiment evaluated the potentials of cocoa pod husk (CPH)-based compost on okra and soil chemical properties. Three CPH-based compost: CPH+ Neem leaf (CPH+ NL), CPH+ Poultry manure (CPH+ PM) and CPH+ PM+ NL were prepared. The treatments; 25, 50, 75, 100 kg N/ha of each compost and NPK mineral fertilizer at 40, 50, 60 kg N/ha and control, were applied to 5 kg soil each and arranged in a completely randomized design in three replicates. Two varieties of okra (NH47-4 and LD88) were grown for six weeks and residual effect evaluated. The Nitrogen, Phosphorus, and Potassium uptake of okra were determined. Pre- and post-cropping soil analyses were done. Data were analyzed using ANOVA and means separated by Duncan Multiple Range Test at α_0.05. The results showed that the nutrient uptake of okra consistently increased with CPH-based compost compared to control in both main and residual cropping. Nitrogen uptake ranged from 53.6 (60 kg N/ha NPK) to 106.7 (50 kg N/ha CPH+ PM) and 16.10 (50 kg N/ha NPK) to 55.06 (25 kg N/ha CPH+ PM+ NL); Phosphorus uptake ranged from 6.9 (25 kg N/ha CPH+ NL) to 24.1 (60 kg N/ha NPK) and 3.70 (25 kg N/ha CPH+ NL) to 9.98 (50 kg N/ha CPH+ PM+ NL), while potassium uptake ranged from 166.4 (25 kg N/ha CPH+ NL) to 244.48 (25 kg N/ha CPH+ PM+ NL) and 64.06 (40 kg N/ha NPK) to 122.29 (75 kg N/ha CPH+ NL) mg/plant in main and residual cropping, respectively. Organic carbon, pH, nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg) and sodium (Na) were also significantly increased by the CPH-based compost. It could, therefore, be concluded that CPH-based compost could be a good fertilizer for okra production.  相似文献
