The greenhouse soil produces green food, which requires loose and soft soil layer, moderate sand adhesion, rich organic matter, good soil and fertilizer, good structure, complete and sufficient nutrients, strong fertilizer and fertilization, large number of microorganisms, high activity, acid and alkali. Suitable, suitable for redox, wet soil, strong water supply, water retention, good ventilation, suitable temperature and other fertility traits. Therefore, high quality organic fertilizers must be applied frequently to maintain and improve soil fertility.
The main raw materials for high-quality fertilizers, we use fresh cow dung, chicken manure, wheat bran and so on. Composting was carried out according to the ratio of 4 parts of cow dung, 4 parts of chicken manure and 2 parts of wheat bran.
First, the pile of rot conditions 1, water: moisture content of 60 ~ 75% of the weight of the pile of rot materials is appropriate, that is, with the iron shovel into a group, throw away. The wheat bran is pre-soaked with enough water before it is mixed with cow dung and chicken manure.
2, ventilation: Because the pre-composting rot is mainly aerobic decomposition, the fertilizer pile should not be pressed too tightly, and some vent holes can be set with corn stalks. In the later stage of the pile rot, the gas is mainly decomposed, and the pile can be compacted and covered with plastic cloth to facilitate the preservation of nutrients and the accumulation of humus.
3, temperature: 55 ° C ~ 65 ° C high temperature for about a week, to promote high temperature microorganisms to strongly decompose organic matter, while killing the bacteria eggs, and then turn over and cool down in time to facilitate moderate temperature microbial activities, promote the conversion of effective nutrients and humus Synthesis.
4. pH: The microorganisms are suitable for activity under neutral to slightly alkaline conditions. Organic matter will produce various organic acids and carbonic acid during the process of composting, so that the acidity in the compost is enhanced, so 5% of plant ash and a small amount are added to the heap of rot materials. Potassium and calcium fertilizer can adjust the pH.
5, carbon to nitrogen ratio: heap rot raw materials, especially wheat ç³ C / N ratio, plus 5% pure NP speed compound fertilizer, can reduce the C / N ratio, promote decomposing, but also preserve N nutrient, improve compost The role of quality.
Second, the fertilizer effect Because of the scientific heap, so, the mature organic fertilizer, soft texture, rich in organic matter, N, P, K and medium and trace elements are homogeneous and sufficient. Both potential nutrients and quick-acting nutrients provide stable and long-lasting fertilizer. Planting melon in a greenhouse for one-time application of base fertilizer not only grows well, has strong disease resistance, large fruit, high sugar content, and does not require topdressing or pesticides in the whole process of melon growth and development. water. Save time and effort, low cost and good economic returns.
