First, increase the mechanism of action. Biogas fertilizer is the residue of biogas fermentation and is recognized as a good quality fertilizer. In addition to abundant nitrogen, phosphorus, and potassium, it also contains trace elements such as boron, copper, iron, manganese, calcium, and zinc that are important for the growth of nectarine trees, as well as a large amount of organic matter, amino acids, and vitamins. Wait. It has the characteristics of a wide range of raw materials, low cost, full nutrients, and long fertilizer efficiency. The application of biogas fertilizer in nectarine garden can meet the nutrients needed for the growth of nectarine, and the nutrients can be easily absorbed and utilized; increase the organic matter in the soil, and can improve the soil structure in successive years, improve the ability of the soil to retain water and fertilizer and resist drought, and increase the yield of nectarine trees ( 20% increase in yield), enhance stress resistance, significantly reduce pests and diseases, uniform fruit size, bright color, delicious and sweet. Gaozhuang Village in Xuzhuang Town in this district uses NF fertilizer to cultivate nectarines, free of chemical fertilizers, fertilizes fertility, improves soil physical and chemical properties, reduces the incidence of pests and diseases, reduces the amount of pesticides, and not only reduces production costs, but also The nectarine has high yield and stable production, good quality, beautiful appearance, delicious taste, and is sold at a price higher than 50% of the same variety.
Second, the application of biogas fertilizer method. There are two kinds of commonly used biogas fertilizer, one for the base fertilizer biogas residue, and the other is for the top dressing and foliar fertilizer biogas slurry.
1, as base fertilizer. Shiji Fei should be carried out in the fruitless period. Generally, the residue is applied as base fertilizer at the end of January to February or November of each year (drainage or large refueling of the digester). According to the size of the peach, each nectarine should be applied to the residue 15 ~ 20 kg. The specific method is: dig 4 to 6 pits around the peach tree, the depth is 30 to 35 centimeters, fertilize, irrigation (the amount of water is 5 times the amount of biogas slag), wait until the water is infiltrated and timely fill the soil to ensure the efficiency of fertilizer and Prevent frostbite roots.
2, for top dressing. The application time of biogas slurry as topdressing is in the period of germination, flowering, fruit setting and fruit period. It is applied 3 to 5 times a year, and each application of biogas slurry is 10 to 20 kg. The specific method is: dig into the groove along the root or dig around the tree 4 to 6 pits, can also be dug into a circular groove, depth 30 cm, width 20 cm, take marsh fertilizer to 5 times the water, applied to In the trenches, the soil shall be covered immediately after the biogas slurry has been dried.
3, spray leaf fertilizer. Fertilizer spraying can be carried out in the bud, flowering, young fruit, and fruit period. The clear and filtered middle biogas slurry is used to spray 10 times more water on the canopy and sprayed once every 10 to 20 days. The back is soaked but the fertilizer solution does not drip. Foliar spray fertilizer can make the nectarine tree thicker, darker color, significantly reduce the occurrence of diseases and insect pests, enhance the tree stress resistance. Combined with the growth of peaches, determine the amount of fertilizer and operating skills. In general, the difference in growth should be re-applied, and the growing trend should be applied lightly; the aging tree should be re-applied, the juvenile trees should be given lightly, and the fruitful replanting should be given less attention. Spraying during fruit growth can increase yield and improve peach quality.
Third, pay attention to matters. 1 When using biogas slurry to spray the nectarine leaf surface, the biogas slurry in the discharge chamber of the biogas digester that normally produces gas for more than 3 months must be used, and it must be clarified and filtered for 2 to 3 days; the biogas fertilizer without adequate fermentation Out of service. 2 When biogas residue and biogas slurry are used as base fertilizer and topdressing, they should keep a certain distance from the roots to prevent excavation and burn of roots. 3 As a basal biogas fertilizer, it should be timely covered after application to prevent the fertility from evaporating. 4 The time for foliar spraying is required to be performed when the temperature is low in the morning or in the afternoon. It is not appropriate to spray at high temperature during noon. 5 When using foliar spray fertilizer, it is necessary to determine the proportion of water to be reasonable according to the concentration of biogas fertilizer so as to avoid causing fertilizer damage. Spray the foliage should focus on the back of the leaves. 6 If pests and diseases occur, pesticides may be mixed into the biogas slurry for spraying.
