Editors also want to "sit on the moon"? That's right! Since the grapes are harvested, the fruit takes away most of the nutrients in the tree. At this time, the vines are as weak as the postpartum mothers, and they need to be supplemented in time to restore the tree. During the "confinement" period, should the fruit farmers make up the vines? Ji Yanzhi, an associate professor at Hebei Agricultural University, suggested that after harvesting fruit and before wintering, it is the grape storage nutrient period. The fruit farmers should apply the organic fertilizer mainly to the vine, and the chemical fertilizer is supplemented by the “moon child fertilizerâ€, which is the early spring tree body in the coming year. Growth provides adequate nutrients. Our reporter Liu Zhenyuan "Like the post-natal mother, after harvesting the grapes until the winter is the storage nutrient period, you need to 'sit the moon' to supplement the nutrients consumed." Ji Yanzhi told reporters, "This time, it is the flower bud differentiation period, and It is the peak period of root growth. The nutrient of the tree is transferred from the fruit before harvesting to the accumulation of the tree itself, so it needs a lot of nutrients. In addition, the temperature and ground temperature at this time are relatively high, and the roots of the tree are easily healed. Month's can effectively promote new roots." The "confinement" in Jiyan Zhikou refers to the application of "moon-fertilizer" to the vines by the fruit farmers after the fruit picking by means of ditch application or applying base fertilizer and spraying foliar fertilizer. "The role of 'moon child fat' is obvious. One is to increase the accumulation of nutrients in the tree; the other is to facilitate the healing of the injured roots and the germination of new roots; the third is to avoid the soil drought caused by fertilization; the fourth is to make the base fertilizer timely Play the fertilizer effect." Ji Yanzhi said. "Moon child fat" should be timely The grape "moon child fat" sounds interesting, and fertilization can be recognized. In general, September to November each year is the best fertilization period for “moon child fertilizerâ€. Ji Yanzhi said: "Base fertilizer autumn is beneficial to increase the accumulation of nutrients in the tree, increase photosynthesis and increase the storage of organic matter of the plant, which is extremely beneficial to the tree potential, fruit yield and quality of the next year." Ji Yanzhi introduced that her research team found in the investigation of Zhuolu County, Hebei Province, that many fruit farmers often ignore the application of “moon child fertilizer†after grape picking: some because winter shearing and burying soil for cold protection immediately after harvesting The time is tight; some because of the fear of trouble, I feel that there is no fruit to be fertilized after picking; some people do not know enough about the effect of "moon child fat". In addition, the research team also found in 15 surveys of 158 households, only 15 households of autumn crops, accounting for 9.5% of the total number of surveys, other farmers are fertilizing in the spring. In this regard, Ji Yanzhi pointed out: "If winter base is applied, it will delay the effect of fertilizer. In the spring, when new shoots and fruits need to grow a lot of nutrients at the same time, they will compete due to insufficient nutrients, reduce the rate of fruit set, and affect flower bud differentiation. , fruit swelling, coloring and sugar content." It can be seen that if the grape “moon child fat†is neglected, it will really “mose a fat fertilizer and affect the three generations of fruitâ€. Ji Yanzhi said that the grape “sitting†is not good for the “moonâ€. Neglecting the tree management in the later stage will lead to premature leaf damage, reduced photosynthesis, and nutrient loss in the tree storage, thus making the early spring nutrient deficiency and germination. It is late and not neat, even leading to flower bud degradation and reduced flowering results. The lack of flowering results will cause the next year's leaves to grow, which will affect the results of the third year. "Moon child fat" to make up "Grape 'moon 'fertilizer' should be based on organic fertilizer, mainly including fermented farmyard manure or commercial organic fertilizer produced by the factory, supplemented by chemical fertilizer." Ji Yanzhi said that the research team is in Hebei Province. The four-year experiment of Laixiang Grape Science and Technology Demonstration Park found that the application of organic fertilizer in autumn was 30% lower than traditional fertilization, but the yield increased by 13.8%. The vitamin C content in fruit was 14.25 mg/100g, which was 40% higher than traditional fertilization. . In fact, Ji Yanzhi also found that the nitrogen, phosphorus and potassium nutrient inputs in the main grape producing areas of Hebei Province were high. The soil organic matter content in the orchard was 9.6~14.3 g/kg, which was in the lack or low level. 74% of the orchard organic fertilizer application in the survey sample was less than 1000 kg/mu. “This shows that many farmers still only pay attention to chemical fertilizers and neglect organic fertilizers.†Ji Yanzhi continued to add, “Of course, it is also important to invest in quantitative fertilizers. For example, fresh grapes, 'sitting the moon', should be based on base fertilizers. The key fertility period is based on the rational application of chemical fertilizers, and the fertilization principle of trace element fertilizer in foliar application." "Moon child fat" to make up How can we make up the post-harvest grape "moon child fat"? Ji Yanzhi said that there are two ways: one is ditch application or acupoint application of base fertilizer, and the other is spraying foliar fertilizer. How to carry out ditch application or point application of base fertilizer? According to Ji Yanzhi, before harvesting, before burying the soil and preventing cold, the peak period of growth and development of grape roots is from mid-November to mid-November. Generally, along the planting line, the two sides are separated by grooves or multiple points, and the tree body is 40 cm away. Fertilization ditch 40 cm deep and 30 cm wide. When ditching, the topsoil and raw soil are open. Before fertilizing, first backfill a layer of topsoil of about 10 cm, apply 1000~1500 kg of organic fertilizer per mu, and then apply 35 kg of special fertilizer for the grapes. Stir the soil and fertilizer evenly. Backfilled with raw soil to the ditch. How to spray foliar fertilizer? She said that before harvesting, before the leaves, generally the end of September to October, the photosynthesis of the leaves enters the second peak, spraying 0.2% urea + 0.2% potassium dihydrogen phosphate every 10 days or so, continuously spraying 2~3 times. . “In addition, we have also proposed soil testing and formula fertilization technology, which makes the grape 'moon child fat' more targeted.†Ji Yanzhi said, “This is based on soil testing and fertilizer field experiments, according to the grape fertilizer requirements, Soil fertilization performance and fertilizer effect, based on the rational application of organic fertilizer, study the quantity, time and method of applying NPK fertilizers." "moon child fat "Do not hurt Make up, make up, don't make up! "Organic fertilizer application or shallow application will increase the amount of fertilizer, grape roots are difficult to lay down, and organic fertilizer is poorly cooked, and it is easy to cause problems such as pests and diseases." Ji Yanzhi explained that on the one hand, excessive application of organic fertilizer will It causes ammonia volatilization and nitrate leaching, which causes the groundwater nitrate content to increase. On the other hand, fresh and unfertilized organic fertilizer will enhance the soil denitrification trend and increase nitrous oxide emissions. Third, excessive application of manure can also cause accumulation of heavy metals in the soil. Excessive application of chemical fertilizers can also cause soil pollution. In particular, nitrogen fertilizer will enter the water body and cause an increase in nitrate content, which will also increase the emission of nitrous oxide in the atmosphere. For example, Ji Yanzhi said that in recent years, the application of nitrogen fertilizer in Hebei Province has reached 75 kg of pure nitrogen per mu, equivalent to 163 kg of urea. After the nitrogen fertilizer is applied to the soil, 15%~46% of the nitrogen remains in the soil, 3%~57% of the volatile loss, 10%~38% of the infiltration loss, and about 70% of the nitrogen fertilizer enters the environment. Caused the deterioration of the ecological environment. "In addition, remember not to use chlorinated fertilizer." Ji Yanzhi reminded, "In fact, the key to the grape 'sitting' good 'moon' is scientific and rational fertilization and tree management."
