Abstract


Three factors and three levels of a randomized block design, using a combination of field trials and laboratory analysis method to carry out the potato and kidney bean intercropping the standardized cultivation technology test aimed proved Guizhou altitudes potato intercropping kidney beans cultivation mode , so as to achieve the purpose of the efficiency of the section, and filter out the optimal combination of selected programs available for actual production. The test results show that: 1. Different intercropping pattern (A) under potato production as follows: the A 3 > A > A 2 2:2 intercropping potato kidney beans the highest yield of potatoes 16.02kg/12m 2 than the A 1 A 2 processing income 4.26kg, 5.44kg, yield 26.6 % and 34.0%. 2. Test deal with kidney beans production levels of processing large differences in test of 27, the average production in the order of precedence, A 3 B 2 C 3 average yield ranked first for 1.55kg/12m 2 : A 1 B 2 2 combination, only 0.87kg/12m 2 , the lowest production levels in all combinations. 3. Potato yield components of Path Analysis results show that the shoot fresh weight yield is the direct effect, the indirect effects of the impact is very small, the various factors to arrive at a direct role in the size of the plot yield: average branch number> Slub diameter> shoot fresh weight> height. 4. Path of the constituent elements of the kidney bean production analysis, the results showed that: the introduction of five agronomic traits kidney bean production: seed weight> number of monoclonal effective pod pod length> biological yield per plant> height. 5. Different intercropping patterns on certain influence on the content of soluble sugar in the potato, three intercropping mode squaring period There was no significant differences, is more and more obvious as the continuation of the growth period, content differences in the budding stage three Intercropping Pattern soluble sugar content: 1:2> 2:2> 2:1, flowering to maturity: 2:2> 2:1> 1:2. The trend of reducing sugar content in tubers of potato at different growth stages in three intercropping model is basically the same, and always: 2:2> 2:1> 1:2. 6. Intercropping system of potatoes and kidney beans, potatoes and kidney beans to 2:2 intercropping, composite highest value to the composite output value for the selection of the target, the best combination of cultivation: A 3 B 2 C 3 , the two lines of the two lines of potato intercropping kidney beans, potato plant spacing of 25cm and kidney bean plant spacing of 40cm.
