Embodiment 1 2011

[0019] Embodiment one, field test in 2011

[0020] 1. High-yield field test results:

[0021] Table 1 result shows, the present invention increases 0.9-1.9 than pure controlled-release fertilizer single plant number of fruits in 2011, and fruit full rate improves 3.4-6.8 percentage points, and rice yield improves 0.8-1.4 percentage points, and the number of kilograms of fruit reduces 8 -23, the yield of pods increased by 6.5%-10.6%, the average yield increased by 7.9%, and the fertilizer utilization rate increased by 6.5-9.0 percentage points.

[0022] Compared with ordinary nitrogen fertilizer, the number of fruits per plant increases by 2..0-3.0, the rate of full fruit increases by 5.3-8.7 percentage points, the rate of rice production increases by 1.6-2.2 percentage points, the number of fruits per kilogram decreases by 30-45, and the yield of pods increases. 13.4%-17.8%, with an average increase of 14.9%. Fertilizer utilization rate increased by 3.1-5.6 percentage points...

Embodiment 2 2012

[0032] Embodiment two, field test in 2012

[0033] 1. High-yield field test results:

[0034] Table 3 results show that the present invention increases 1.2-2.0 in 2012 compared with pure controlled-release fertilizer single plant number of fruits, the full fruit rate improves 1.1-2.6 percentage points, the rice production rate improves 0.8-1.4 percentage points, and the number of kilograms of fruits reduces by 9 -26, the pod yield increased by 5.4%-7.8%, with an average increase of 6.4%. Fertilizer utilization rate increased by 7.1-8.7 percentage points.

[0035] Compared with ordinary nitrogen fertilizer, the number of fruits per plant increased by 2.1-2.9, the rate of full fruit increased by 2.2-3.7 percentage points, the rate of rice production increased by 1.5-2.1 percentage points, the number of fruits per kilogram decreased by 27-44, and the yield of pods increased by 15.4-18.0 %, with an average increase of 16.5%. Fertilizer utilization rate increased by 2.9-4.5 perc...

Abstract

The invention discloses a long-lasting nitrogen special fertilizer formula for peanuts. The formula comprises 35-38% by weight of ordinary nitrogen fertilizer, 25-28% of 60-day controlled release fertilizer, 20-23% of 90-day controlled release fertilizer and 15-18% of 120-day controlled release fertilizer. The long-lasting nitrogen special fertilizer formula for the peanuts, provided by the invention, can perform sustained and stable supply against the requirements for the nitrogen fertilizer of the peanuts during the growth and development processes, prevent affecting nitrogen fixation of rhizobia and normal growth and development of plants due to too high nitrogen concentration in soil in a certain period of time, and further prevent affecting the growth and development of the plants due to insufficient nitrogen concentration in the soil in a certain period of time so as to realize supply according to requirements, and further has important application values.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a long-acting nitrogen-special fertilizer formula for peanuts. Background technique [0002] Slow-release nitrogen fertilizer is a new type of fertilizer developed in recent years. It has the characteristics of less loss, strong fertilizer efficiency and high fertilizer utilization rate. Therefore, it can save fertilizer, protect the environment, and prevent crops from defertilizing and premature aging. [0003] At present, the release period of peanut slow-release fertilizer is generally about 120 days, and the application method is generally to apply pure slow-release fertilizer, or ordinary nitrogen fertilizer and slow-release fertilizer each account for about 50%. Both of these two fertilization methods have certain problems. The fertilization effect of the former is mainly in the late growth period, ignoring the nitrogen fertilizer supply in the early and mid...
