First, the application time of nitrogen fertilizer
1. Many farmers feel that "N fertilizer application in the spring can be effective for flowering and fruition in the year." In fact, this view is wrong. There are two effective states of nitrogen: nitrate nitrogen and ammonium nitrogen. After the fruit tree absorbs nitrogen fertilizer, these two states will be converted into nitrate, nitrogen dioxide, carbohydrates, and amino acids and stored in the tree. This process is not fast enough to complete, so the application of nitrogen fertilizer in the spring is ineffective for flowering results and flower bud differentiation in the current year.
2, the best application time of nitrogen fertilizer: autumn application (before the fall of fruit trees).
3, optional nitrogen fertilizer: Tiansheng gold peptide (containing organic nitrogen nutrition, can be directly used without conversion).
Second, the depth of fertilization
1, for the depth of fertilization, many people when fertilizing, according to the "fertilizer should be deep, in order to prevent loss," the fertilization of the common saying, but to know that this view is wrong, not worth pushing.
2. After fertilizing fruit trees, many mineral elements that dissolve in water, such as calcium, potassium, etc., should be leaked with the water after watering, seep to the depth of the soil to a certain depth, and the more times water is poured, Leakage is getting worse.
3. The depth of traditional fertilization methods is generally 40-50cm. After fertilization, the leakage is serious as the number of irrigation times increases, and the fertilizer utilization rate is severely reduced.
4. When fertilizing fruit trees, regardless of whether it is applied to the base fertilizer or top dressing, the shallow root system of fruit trees should be considered. The most suitable depth for fertilization is within 10-20 cm below the surface.
Third, the depth of cultivator
1. It is wrong to say that "the cultivator should be deeper to increase the conservation effect and suppress weeds."
2. Protecting the roots of 10-20cm below the ground of fruit trees will help promote flower bud differentiation and improve fruit quality.
3. When cultivating the fruit in the orchard, cut the soil surface and cut off the capillary in the soil.
IV. Ways of irrigation
1. When the orchard is watering, it must not be flooded with water. This can lead to the death of pear fibrous roots and the hardening of the soil.
2, drip irrigation or drip irrigation.
3, drip irrigation or irrigation advantages: water, labor, time, reduce disease incidence.
