Perennial medicinal plants of fruits such as alfalfa, hawthorn, sorghum, ebony, ginkgo, jujube, lime, fig, etc., with fruits as harvest objects, and their life cycle is very long, resulting in an economic period of 20 to 50 years, 1 year The growth, flowering and fruiting period lasts for 6 to 8 months. Therefore, in order to obtain stable and high yield in production, it is necessary to apply a certain amount and quality of fertilizer frequently and timely to supplement the deficiency of soil nutrients and meet the needs of plant growth and development. There are two kinds of fertilization for medicinal fruit trees: soil fertilization and extra-root fertilization. Pay attention to the following points when fertilizing fruit trees:
The combination of nutrient elements and medicinal fruit trees requires more than ten kinds of nutrients. When fertilizing, it can be fertilized by reference to the local orchard fertilization method or after field trials using appropriate fertilizer formula. The base fertilizer is mainly based on farmyard manure, supplemented by a little compound fertilizer or special fertilizer for fruit trees. The topdressing fertilizer is mainly based on quick-acting nitrogen fertilizer, and appropriate boron, zinc, manganese, iron and other trace elements are added to meet the demand of various nutrients for tree growth. The yield of medicinal materials obtained by mixed fertilization is higher than that of single fertilisers.
The fertilization amount of medicinal fruit trees is related to tree species, varieties and soil conditions. The fruit trees such as alfalfa, hawthorn and ginkgo need relatively large amount of fertilizer, and the fruit trees with thin or fruity periods such as mountains and sandy land can be appropriately applied. Generally speaking, the base fertilizer based on farmyard manure should be no less than 50kg per plant per plant. When urea is applied, small trees are applied less and trees are applied more. The young trees are 0.2kg per plant, and the adult tree can be chased. Apply about 0.5kg.
In the fertilization period, the base fertilizer can be combined with deep tillage and soil improvement in winter. At this time, the base fertilizer can protect the plants in the cold winter, and on the other hand, the base fertilizer can be fully decomposed before the spring plants begin to absorb, and at the end of autumn and winter. When the plants enter a dormant period, the sap stops flowing and the damage to the roots of the plants is small. The topdressing principle is based on a small number of times. The adult result tree needs to be topdressed 2 to 4 times a year:
Pre-flowering topdressing The medicinal fruit tree flowering period is positive for the nutrient distribution period (centered on the reproductive organs) and is sensitive to nitrogen fertilizer. The application of nitrogen fertilizer can reduce the fruit drop and increase the fruit setting rate.
Post-flowering topdressing Young fruit requires nitrogen fertilizer in the rapid growth period. If the pre-flowering fertilizer is applied too much, it can be applied less or not.
Fruit enlargement and flower bud differentiation period of topdressing Flower buds begin to differentiate during the fruit expansion period. This top dressing can not only ensure the current year's output, but also overcome the effect of years of results, laying a good foundation for production in the coming year. The ratio of topdressing NPK fertilizer is 1:0.5:0.5.
After the fruit growth, the medicinal fruit trees consume a lot of nutrients after the results. This time, the topdressing is particularly important, which can restore the nutrient level of the tree, enhance antibiotics and safely overwinter.
Fertilization method In the process of fertilization, various methods are replaced, so that the fertilizer effect can be fully exerted, and the roots in all directions can be obtained nutrients, thereby promoting tree growth and crown crowning uniformity:
Fertilization in the whole garden Dwarf and densely planted medicinal fruit trees can spread the fertilizer directly in the whole garden and then turn into the soil. This can lead the roots into the soil layer, promote the formation of strong roots and a large number of fibrous roots, and strengthen the ability to absorb water.
Irrigation Fertilization Use the channels or pipes to transport fertilizer to the medicine garden for fertigation.
Ditch fertilization An annular groove of 20-40 cm deep and wide is excavated between the rows of fruit trees. After applying the base fertilizer, the soil cover is used to prevent soil erosion. This method is mostly used for sapling winter fertilization.
Apply a hole in the outer edge of the canopy to dig 4 to 8 deep 40cm holes, apply the top dressing and fill it.
The above-ground organs of the topdressing fruit trees can also absorb nutrients, among which the young leaves have the strongest absorption capacity, followed by young fruit, mature leaves and old branches. In view of this principle, fruit trees are often planted by root dressing to make up the roots. Insufficient fertilization. As a supplement to soil fertilization, a solution of the fertilizer is sprayed on the surface of the fruit leaf by spraying. The root-fighting fertilizer has quick effect and is used in provinces. It is mainly used for “small old trees†or “old trees†to rescue trees and restore vitality; or due to excessive results, temporary de-fertilization to accelerate the supply of nutrients; Elemental deficiency; or for the purpose of preserving fruit and fruit. The method is mostly applied to nitrogen fertilizer and micro-fertilizers such as boron, zinc, manganese and iron. The concentration is: urea 0.5%, potassium dihydrogen phosphate 0.3% to 1%, superphosphate calcium leaching solution 1% to 3%, borax 0.05 % to 0.1%, zinc sulfate 0.1% to 0.6%, magnesium sulfate 2% to 3%, 50 ppm gibberellin, and the like.
