Background

Areca catechu (scientific name: Areca catechu L.) is a evergreen tree of Areca genus of Palmae family, native to Malaysia, and widely cultivated in tropical regions of Asia. In China, betel nuts are mainly distributed in the tropical areas of Yunnan, Hainan and Taiwan. At present, seed propagation is mostly adopted in a main betel nut producing area. The seeds are bagged and cultivated after germination acceleration on a seedbed, and are planted in a field after the height of the betel nut seedlings reaches about 45 cm.

The production period of the betel nuts is as long as 30-40 years, and the selection of high-quality seedlings is a prerequisite condition for efficient cultivation. The support basis for cultivating high-quality seedlings is the selection of seedling culture substrates. The seedling raising matrix not only directly influences the growth speed and quality of seedlings, but also influences the seedling recovery, flowering and fruiting and fresh fruit yield of the betel nuts after field planting. The substrate is a basic substance widely applied in the seedling raising process, and not only needs to consider the requirements of plants on nutrient substances, but also needs to consider the influences of the water retention property, the air permeability and the like of the substrate on the growth of plant roots.

Betel nut seedlings generally need to be cultivated in nursery bags for 0.5-1.5 years from germination of the betel nuts until transplantation to the field. Although the history of planting Hainan areca nuts has been over 2100 years, scientific management is less conscious. Most farmers randomly take 'hand soil' to bag and grow seedlings, so that nutrient deficiency or unbalance is easily caused, and the requirement for growth of areca seedlings is difficult to meet in the whole seedling growing process. In addition, the phenomenon that the water and fertilizer management is not in place or is completely irrespectively carried out in the seedling stage of the betel nuts is very common.

Therefore, the special fertilizer for disease resistance and growth promotion of the betel nuts and the preparation method thereof are provided, have the functions of improving soil, promoting the growth of betel nut plants and enhancing the disease and pest resistance of the betel nuts, and are a novel environment-friendly biological organic fertilizer with green and lasting fertilizer efficiency.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

example (b):

the invention provides a preparation method of a special disease-resistant growth-promoting fertilizer for areca nuts, which comprises the following steps of:

(1) and raw material pretreatment: mixing 15% of chicken manure, 35% of sheep manure, 20% of bagasse, 15% of cane mud and 10% of straws in a mixer, feeding the mixed raw materials into a primary fermentation tank for primary fermentation, and carrying out aeration and turning treatment on the raw materials in the primary fermentation process;

(2) feeding the raw materials subjected to primary fermentation into a secondary fermentation tank for secondary fermentation, and performing aeration and turning treatment on the raw materials in the primary and secondary fermentation processes to facilitate further decomposition of the raw materials;

(3) collecting and concentrating odor generated in the primary fermentation and the secondary fermentation, and discharging the odor after the odor reaches the discharge standard;

(4) adding 5% of compound microbial agent into the secondary fermented and decomposed fertilizer, and uniformly stirring to form a special fertilizer for the betelnut;

(5) and crushing, screening, metering and packaging the special fertilizer for the betel nuts to form a special fertilizer product for the betel nuts.

Wherein, the odor collection treatment, the crushing, the measurement and the packaging after the sieving can be carried out according to the requirements, but not necessary steps.

Example 1

The application conditions of the prepared special fertilizer for betel nuts are as follows:

(1) application time: before sowing, the soil is turned over to be used as base fertilizer or base fertilizer, after the base fertilizer is applied, the soil is fully mixed with the soil, and the soil is immediately covered, so that the sowing and planting can be carried out after one week.

(2) The application method comprises the following steps: the method of hole application or furrow application is adopted, and soil is covered after application at a position 50-80cm away from the betel nut stem, namely the periphery of the root system, so as to avoid applying fertilizer at the same position.

(3) Fertilizing amount:

a. young trees: the growth of young areca is mainly the vegetative growth of roots, stems and leaves, and needs more nitrogen, and the fertilization is mainly nitrogen fertilizer. Generally, the fertilizer is applied for 3 times per year, 5kg of special fertilizer for the betel nuts and 0.2-0.3kg of phosphate fertilizer are applied for each time, trenches with the depth of 30 cm are formed on two sides of the crown of the betel nut before the fertilizer is applied, and then the fertilizer is deeply applied and returned to the soil. Along with the growth of plants, the total annual fertilization amount is increased year by year, 0.5-0.6kg of nitrogen, phosphorus and potassium compound fertilizer is applied per plant, and the dosage of potassium chloride is increased 1 year before fruit harvest, and 0.2kg of potassium chloride is applied per plant each time.

b. Mature tree: the vegetative growth and reproductive growth of the areca nuts of the grown-up trees are carried out simultaneously, and the demand for potassium is high, so the grown-up trees are mainly applied with potassium fertilizer and phosphate fertilizer and are supplemented with nitrogen fertilizer. It is generally applied 3 times per year. The 1 st time is a pre-flowering fertilizer, and 8-10kg of special fertilizer for betel nuts and 0.15kg of potassium chloride are applied before 2 months of flowering; the green fruit fertilizer is applied for the 2 nd time, the leaves grow vigorously in the period, the fruits are rapidly enlarged, more nitrogen is needed, 8-10kg of special fertilizer for areca nuts, 0.2kg of urea and 0.2kg of potassium chloride are applied for areca nuts, or 0.3kg of nitrogen-phosphorus-potassium compound fertilizer is applied for areca nuts; the 3 rd time is winter fertilizer, mainly applying potassium fertilizer, and applying 8-10kg of special fertilizer for betel nut, 0.5-1.0 kg of phosphate fertilizer and 0.2kg of potassium chloride per plant in 11 months.
