Before planting vegetables, base manure is an essential measure. The manure commonly used by farmers is chicken manure, pig manure, rice manure and straw manure. For chicken dung, there are sticky chicken droppings, sand chicken droppings, rice husk chicken droppings and dried chicken droppings. Do not look at chicken manure, its application effect is very different. Therefore, it is very important to choose a suitable chicken dung according to the actual situation of your own shed. However, when farmers choose to use these manures, most of them rely on their own preferences and habits. Few people consider what kind of manure is best for their own shed. So, what are the advantages of manure in selective application? The author believes that the most important point is that the type of manure should be selected according to the soil of the shed. Basically, the following points should be noted:
1. Sandy sheds should use sticky chicken manure or sticky pig manure. This chicken manure and pig manure, also known as pure chicken manure and pure pig manure, contain no impurities such as sand and rice husk, and has high purity and high nutrient content. The most important of these is the high content of organic matter, because this kind of manure is more viscous and has a good effect on the leakage of sand and fertilizers. Therefore, the author suggests that the sandy shed should be selected from sticky chicken manure or viscous pig manure. Different crops require different fertilizers, and it is generally advisable to apply 15 to 20 square meters per shed.
2. Sandy chicken manure or sand pig manure should be used in clay land. Everyone knows that clay land is very difficult to cultivate, and soil permeability is not good. Therefore, it is best to use sand chicken excrement or sand pig excrement when manure is applied in this kind of shed. This dung is formed by sand farmers using sand washers in the cultivation process, and the sediment content is high. After applying it to clay, it has a very good improvement effect. Due to the high sediment content of chicken manure or pig manure, the fertilizer effect is relatively low, and it is generally appropriate to apply 30 kilograms per acre.
Third, soil compaction, high degree of salinization, poor permeability of the soil should use rice husk manure or straw fertilizer. In particular, like some old sheds that have been planted for many years, the soil is severely hardened and the degree of salinization is high, and a lot of red frost is formed on the ground surface. Like this soil, vegetables are difficult to grow well after colonization, and roots often suffer from multiple diseases due to poor ventilation. Dead trees continue. Therefore, this kind of soil is best to use rice husk manure or straw manure, because this kind of manure contains high organic matter, and after use, it can not only ensure nutrient-rich vegetables, but also achieve ideal soil improvement effect. Under normal circumstances, this type of manure is suitable for about 40 square meters per acre.
To sum up, the purpose of applying manure fertilizer can not only consider the supply, but also consider the change of soil, both in order to achieve the desired effect.
