Description

Special fertilizer for tea chrysanthemum

technical field

The invention belongs to fertilizer for flowers, in particular to a special fertilizer for chrysanthemums used in tea.

Background technique

The nutrient management of chrysanthemum for tea generally uses field crop fertilizers, namely organic fertilizers and inorganic fertilizers. Organic fertilizers are mainly human and animal manures. The accumulation, retting, fermentation, processing techniques and application are still at a very primitive level. They are dirty and tiring, and cannot form factory production, and cannot meet the needs of commercial production of tea chrysanthemums; The production cost of these organic fertilizers is high, and the utilization efficiency of the effective components of fertilizers is low, so it is difficult to meet the nutritional needs of tea chrysanthemums; organic fertilizers, especially human and livestock manure, have not been sterilized, causing serious substrate biological pollution and environmental pollution, and tea The health care effect of chrysanthemum is opposite. Inorganic fertilizers are mainly replaced by crop chemical fertilizers or compound fertilizers, which lead to increased fertilizer costs, poor fertilization effects, and affected the yield and quality of tea chrysanthemums, thereby reducing the commodity value of tea chrysanthemums. In addition, most of the fertilization of chrysanthemums for tea in production is still empirical fertilization, which does not meet the requirements of standardized metering formula and balanced fertilization of modern chrysanthemums for tea. Although there are also some flower fertilizers on the market made by non-professional manufacturers, professional agricultural fertilizer manufacturers, or individual operators, and even labeled as "special fertilizers for chrysanthemums for tea", they are often simply produced by manufacturers using several simple chemical fertilizers. Very rough fertilizers that are mixed and packaged in small packages. These fertilizers have various disadvantages due to their low technological content and lack of development based on the nutritional characteristics of tea chrysanthemums and the characteristics of the symbiotic cycle of soil-nutrient-tea chrysanthemums. Its production cost is high, and the application effect is not significant. Therefore, aiming at the unique cultivation method of tea chrysanthemum, developing and producing high-efficiency, slow-release, hygienic, light and economical special fertilizer for tea chrysanthemum is an urgent need to adapt to the production of modern flowers.

Contents of the invention

The object of the present invention is to provide a special fertilizer for tea chrysanthemums with high efficiency, slow release, sanitation, lightness and economy, so as to solve the above problems.

The technical scheme of the present invention is: to meet the normal growth, development and flowering of each chrysanthemum for tea. It is composed of fertilizers applied during the cultivation and growth of chrysanthemums. The weight ratio of its active ingredients is: nitrogen 21.69-25.65, potassium oxide 28.44- 34.50, calcium 13.76-21.00, magnesium 1.05-1.99, manganese 0.76-1.31, iron 0.16-0.27, copper 0.42-0.44, zinc 0.61-0.96, boron 1.75-3.82, and molybdenum 0.08-0.09. Nitrogen mainly comes from urea, potassium oxide mainly comes from potassium chloride or potassium sulfate, calcium comes from calcium nitrate or calcium carbonate, magnesium comes from magnesium sulfate, manganese comes from manganese sulfate monohydrate, iron comes from ferrous sulfate heptahydrate, copper comes from sulfuric acid pentahydrate Copper, zinc from zinc sulfate monohydrate, boron from boric acid or borax, and molybdenum from ammonium molybdate.

According to the nutrient supply characteristics of the tea chrysanthemum soil and the growth and development status of the tea chrysanthemum, the fertilizer mixes large, medium and micronutrients in an appropriate proportion. The chrysanthemum absorbs nutrients regularly, and the fertilizer utilization rate is high, which can significantly improve the growth of chrysanthemum for tea, prolong the growth period, enhance the resistance of chrysanthemum for tea to high temperature, low temperature, drought and other abiotic stress adversities, and improve the potency of chrysanthemum for tea. Yield and quality as well as the health function to the human body.

During tea chrysanthemum cultivation:

1. When preparing the soil, add base fertilizer as the base fertilizer (according to the growth and development characteristics of tea chrysanthemum, it is recommended that the base fertilizer be composed of 200kg/ ^666.7m2 and 52.3kg/ ^666.7m2 of fully crushed rapeseed cake).

2. At the young seedling stage one week after planting and survival, the fertilizer should not be too thick, and special fertilizer for tea chrysanthemum can be applied once.

3. During the period of vigorous vegetative growth, special fertilizer for tea chrysanthemum can be applied twice.

4. About half a month after the head is fixed, the special fertilizer for tea chrysanthemum can be applied once to facilitate the formation of flower buds.

5. After the flower buds are formed, the special fertilizer for tea chrysanthemum can be applied once, but the leaves should be avoided.

6. After fertilization, the soil should be kept moist.

7. When fertilizing, it is necessary to loosen the soil and weed in time to maintain soil permeability.

8. If the chrysanthemum leaves are too thick and large, and when they roll back and droop, it means that there is more than enough fertilizer and should be restrained.
