Magnesium Boron Fertilizer on Yield of Rape Preliminary Report


Fan Zone field management practices and other general management with the local 2 Results 2.1 Field observations show that the experimental field are in the 21102 area of rape 21 years lO emergence, December 24, 2002 (winter solstice) to 9 ~ 10 winter leaves, January 25, 2003 bud,[link widoczny dla zalogowanych], March 15, 2003 flowering. Thus, application of boron and magnesium on the growth of rape seedling no adverse effects. 2.2 The application of boron and magnesium fertilizer on rapeseed yield 2.2.1 can be seen from Table 1, application of boron and magnesium fertilizer on rapeseed plant height, length of main inflorescence, number of primary branches, secondary branches and other tables in the out of 13 targets to increase the role of varying degrees, of which the whole plant on the average grain weight and pod number two most obvious indicators of the increasing role. (1),[link widoczny dla zalogowanych], (2) processing of grain weight were increased by 0.21g and 0.29g, the rate of increase was 6.0% and 8.3%; average pods whole plant were increased by 10.3 and 29.5 / plant, the rate of increase was 5.0% and 14.4%. Increase of the role of whole-plant average pod not obvious. About the author: Dai Huaqin (1971 a), male, Anhui langxi people,[link widoczny dla zalogowanych], agriculture degree, agronomists, mainly engaged in agricultural extension work. Received Date: 2o03.07.01 AGRICULTURAL 2.2.2 2003 can also be seen from Table 1, the same as in the case of application, the application of boron and magnesium fertilizer on rapeseed secondary branches, main stem of the average per pod, pod number average primary branches, the average pod primary branches, secondary branches per pod, pod number average of the whole plant, whole plant per pod yield factors such as increased Effect of boron application increase was significantly lower than the effect. Processing (1) the increase in the value of 7 indexes were 0.2,[link widoczny dla zalogowanych], 0.1 / angle, 0 Ao, 0.1 / angle, 0.2 / angle, 10.3, 0 .1 grain / angle, treatment (3) the increase in the seven index values were 1.1, 1.2 / angle, 2.3 Ao, 0.6 / angle, 0.8 / angle, 27.3 / plant, 0.7 / angle; processing (2) refers to the angle of the 7, 0.6 / angle, 29.5, 0.4 / angle; processing (4) 7 indexes of the increase in the values were 1.4,[link widoczny dla zalogowanych], 1.7 / angle, 2.4 Ao, 0.7 / angle, 0.8 / angle, 55.2, 0.9 particles / angle, but no increase in fertilizer effect of boron on grain weight, and its yield mainly by increasing the rape of the whole plant and average pod number per pod, as well. 2.2.3 Production test results showed that application of boron and magnesium fertilizer on rapeseed yield to a certain extent, (1), (2) increase rates of treatment were 12.0%, 26.7%; but in the application the same way under the premise of Boron Fertilizer on the Yield of magnesium and boron on the yield is less than application. Processing (1) 12.0% increase compared with the control. Processing (3) 16.8% increase compared with the control; processing (2) 26.7% increase compared with the control, treatment (4) 31.4% increase compared with the control. 2.2.4 Demonstration Area Rape average chattels 1459.2kg/hm2. Demonstration outside the conventional method grown locally applied boron 7.5l ��g/11m2, for the average real yield of rape basal 1508.25l 'g/11m2, rape is not the average applied boron chattels 1311.45l ��g/11m2. Large area of application of fertilizer can increase the yield of boron and magnesium 147.75kg/11m2, increase rate was 11.3%; increase the yield of large area application of boron 196.8l ��g/hm2, increase rate was 15.0%, increase rate in boron and magnesium fertilizer. 3 Discussion and summary 3.1 test, demonstration that application of boron and magnesium fertilizer on rapeseed germination and growth without adverse effects, and have a more significant yield, yield rate of 10% or more, but in the case of application in the same way, the increase Effect of boron less. 3.2 Boron magnesium fertilizer on rapeseed yield mainly by increasing the average grain weight and improve the whole plant pod number 2 to reflect the yield factor, boron and magnesium fertilizer on rapeseed per pod increased effect is not obvious. 3.3 In the case of applying the same method, boron and magnesium fertilizer on rapeseed secondary branches, main stem per pod, pod number average primary branches, one branch per pod, the second branch per pod, pod number average whole plant, whole plant yield per pod and other factors increase the effect of less than boron. 3.4 The test plots rape emergence time late, and rape continued after sowing, drought, inadequate soil moisture, fertilizer is not applied boron and magnesium caused by the emergence of rape adverse effects. 3.5 The test is not set gradient, the optimum dosage be studied.
