Problems in cultivation and management are also becoming more and more prominent, and there is a common practice of "heavy production and light management", among which fertilization management has become one of the key links that restrict production and benefit improvement, mainly due to the long-term influence of traditional management habits on the one hand. , most of the bamboo forests have not paid attention to fertilization and neglected fertilization management, resulting in poor growth and low yield; It has a lot of blindness, and there are common problems such as single fertilization or ordinary compound fertilizers that are not highly targeted, resulting in poor fertilizer efficiency and poor economic benefits, and it is difficult to achieve the expected results

preparation example Construction
[0018] 1. Preparation of special compound fertilizer for alder
[0019] Carry out batching according to the example formula of the following examples, fully mix and evenly granulate. According to the random block test method field test, each embodiment selects 30 strains whose site conditions and growth potential are basically the same, and as a block, carry out 4 repeated tests. Fertilizers were applied at a time from the end of March to the beginning of April at a rate of 0.15kg / plant to 0.40kg / plant, and the effect of the formulated fertilizer was statistically analyzed.
Embodiment 1
[0021] For acidic soil, 43 parts of organic fertilizer, 25 parts of urea, 11 parts of monoammonium phosphate, 12 parts of potassium chloride, ferrous sulfate (FeSO 4 .7H 2 O) 1.5 parts, zinc sulfate (ZnSO 4 .7H 2 O) 0.5 parts, clay or bentonite 7.0 parts.
Embodiment 2
[0023] For alkaline soil, 36 parts of organic matter, 30 parts of urea, 12 parts of monoammonium phosphate, 7 parts of potassium chloride, ferrous sulfate (FeSO 4 .7H 2 O) 4.0 parts, zinc sulfate (ZnSO 4 .7H 2 O) 1.0 parts, 10 parts of clay or bentonite.

Abstract
The invention relates to a compound fertilizer specially used for alder. The compound fertilizer includes, by weight, 35-45 parts of an organic fertilizer, 45-54 parts of a macroelement fertilizer, 1-5 parts of a trace element fertilizer and 5-10 parts of clay or a binder. The compound fertilizer contains nutrients required by alder. Formulas for various soil conditions of ecological environmentsof alder are taken into account in the invention, wherein a calcium magnesium phosphate fertilizer or monoammonium phosphate is added for acidic soil to reduce and neutralize acidity of soil; for alkaline soil, monoammonium phosphate or calcium phosphate is added to reduce and neutralize alkalinity of soil; and for neutral soil, it is suggested that the formula for acidic soil should be adopted. The formulas are comprehensive in nutrition, organic matters improve soil, and the compound fertilizer combines inorganic and organic fertilizer, has high specificity, and can fill the gap of compoundfertilizers specially used for alder.
Description
technical field [0001] The invention specifically relates to a special compound fertilizer for alder, which belongs to the technical field of soil fertilizer. Background technique [0002] Alnus cremastogyne Burk (Alnus cremastogyne Burk) is a plant of the genus Alnus (Alnus) in the family Betulaceae (Betulaceae). one. Alder grows rapidly, reproduces easily, has a well-developed root system, has root nodules, is resistant to water and humidity, has a short leaf defoliation period, and has high nitrogen content in leaves. , is also the most ideal companion tree species for fir, pine, and cypress, and has multiple uses such as fuelwood, industrial raw materials, and soil cultivation. Alder is a good material, light reddish-brown wood, no significant difference between heartwood and sapwood, moderate hardness, straight grain, fine structure, and can be used as wood-based panels, papermaking, musical instruments, furniture and other materials. After long-term development, it ...
