1. Bio-organic fertilizer preparation and nursery nutrient soil The nursery nutrient soil requires loose texture, good gas permeability, sufficient nutrients, and strong water retention and fertility. The general method for preparing nursery nutrient soil is to use 60% of vegetable garden soil, 60% of fine sand, 20% of bio-organic fertilizer, and sieving, and adding appropriate amount of NPK. nutrient. The amount of available nutrients is controlled at 150-300 mg/kg for quick-acting nitrogen, 200-500 mg/kg for phosphorus pentoxide, and 400-600 mg/kg for potassium oxide. The amount of chemical fertilizer added to the nursery soil can be calculated according to the effective nutrient content. Generally, 100 kg of superphosphate, 0.2 kg of potassium sulfate and 0.5 kg of ammonium sulfate are added to the 100 kg soil. If bed soil seedlings are used, generally 2 kg of bio-organic fertilizer per square meter of seedbed soil is used, and the soil in the plough layer is uniformly mixed after sowing and then sown.
2. Application method and application amount of bio-organic fertilizer Solanum vegetables include tomato, eggplant, pepper, etc., which are fruits of harvested fruits, and are vegetables that are warm and fertile. According to the growth stage, the method of applying base fertilizer, applying fertilizer strips, transplanting fertilizer points, and dip roots is generally adopted. The application rate of bio-organic fertilizer should be scientifically determined according to the needs of different vegetables and the soil nutrient status, in order to achieve the purpose of increasing production and income.
2.1 Method and dosage of tomato bio-organic fertilizer The root group of tomato is more developed, and the amount of fertilizer needs to be larger. The loamy soil with fertile soil, water retention and fertility should be selected. Before the ploughing of the whole land, the application of bio-organic fertilizer per 667 square meters is 200-250 kg, with 40-50 kg of calcium phosphate and 15 kg of potassium sulfate. The early maturing varieties have a short growing period, and after the first inflorescence, the fruit can be topdressed once, and the organic fertilizer is applied to 40 to 50 kilograms per 667 square meters. Generally, the shallow ditch is applied between the rows of the plants, and the soil is covered; The late-maturing variety will apply 40 kg of bio-organic fertilizer per 667 square meters in the first panicle fruit expansion period, and watering with topdressing fertilizer once. After the second, second and fourth fruit fruiting period, 8-10 kg of urea per 667 square meters in turn, watering after fertilization. In the afternoon of the sunny day when the fruit was selected, it was sprayed with 0.4% potassium dihydrogen phosphate.
2.2 Method and dosage of bio-organic fertilizer for eggplant Eggplant is a favorite fertilizer crop. The soil condition and fertilization level have a great influence on the fruit setting rate of eggplant. When the nutritional conditions are good, there are fewer flowers. Malnutrition will increase the short-column flower, the flower is poorly developed, and it is not suitable for fruit. Before transplanting, apply 200-250 kg of bio-organic fertilizer per 667 square meters, apply 25-35 kg of calcium phosphate, 15-20 kg of potassium sulfate, spread the soil surface, and mix it into the ploughed soil evenly. When the “door eggplant†reaches the “eye-opening periodâ€, the fruit begins to grow rapidly, and the first top dressing is carried out, and 20 to 30 kilograms of bio-organic fertilizer is applied per 667 square meters. A second top dressing is carried out when the fruit of the eggplant is inflated. When the "four-door bucket" began to develop, it was the peak of eggplant requiring fertilizer, and the third top dressing was carried out. The amount of topdressing for the three times is the same, and the amount of topdressing can be halved in the future.
2.3 Methods and dosage of applying bio-organic fertilizer to peppers In various periods of growth and development of peppers, it is necessary to apply different types and amounts of fertilizers according to the requirements of nutrients, and implement scientific topdressing. Do "one control, two promotion, three insurance, four bogey". The so-called one control: control the fertilization during the flowering period, so as not to fall flowers, deciduous, and fruit drop; second promotion: the young fruit period and the harvesting period should be topdressed in time to promote the rapid expansion of young fruit; three guarantees: not to lose fat, not long, not fat Harm; four bogey: avoid using high-concentration fertilizer, avoid wet soil topdressing, avoid topdressing at high temperatures, avoid too concentrated topdressing. The role of the base fertilizer is to promote the growth of the seedlings after slow seedlings, to seal the ridges in advance, and to capture the high yield of peppers. Before the ploughing, every 667 square meters of application or ditch application of bio-organic fertilizer 200 ~ 400 kg, with the application of potassium sulfate 10 kg. In the young fruit period, the first top dressing can be carried out, and 1500 kg of decomposed manure water is applied per 667 square meters. The harvesting period should be chased and rushed. In the sunny day, every 7 to 6 days, 700 kilograms of decomposed manure should be applied every 667 square meters in the morning or evening, and watering and topdressing should be good.
In the process of applying bio-organic fertilizer, it should be noted that it cannot be mixed with a fertilizer such as ammonium nitrate or a basic fertilizer such as ammonium bicarbonate or a physiological alkaline fertilizer such as sodium nitrate. Otherwise, the nitrogen volatilization loss will affect the use of bio-organic fertilizer and fertilizer. Through the use of bio-organic fertilizer, it can effectively improve the nutritional quality of vegetables, activate soil nutrients, improve soil, improve soil fertility, enhance soil water retention and fertility, and promote vegetable growth.
