The latest course of fertilization techniques and methods for nectarines

Nectarine fertilization is the best way to help nectarine grow to obtain high yield and high quality. However, there are different methods to fertilize nectarine trees in different periods, and it should be based on different varieties, environments, transporting ages and soil conditions, as well as nectarine growth characteristics and fertilizer requirements, to comprehensively consider and determine the amount of fertilizer, the type of fertilization and the method of fertilization.

I. Fertilizer demand

At present, most of the varieties planted in nectarine are dwarf varieties, their roots are not deep, there are no obvious main roots, mainly distributed horizontally in the soil of 10 to 40 cm, probably in the periphery of the crown. Therefore, fertilization can mainly take the ring groove fertilizer method, and the depth of fertilization should be the depth that the root system can reach; the root oxygen demand is more, the soil can not be sticky; pH value below 4.5 is easy to lack calcium, phosphorus, magnesium, pH above 7.5 will be deficient in iron, zinc, manganese, resulting in element deficiency.

2. Fertilization technology

1. Young tree

Mainly apply sufficient base fertilizer before planting, generally little or no topdressing. When planting basic fertilizer, you should apply about 500 jin of farm manure per mu, compost, compost, as long as it is mature and fermented, but do not apply high-heat poultry manure. The amount of fertilizer applied is about 70% of that of the whole year. Adequate application of basic fertilizer to ensure the growth of young trees, young trees do not bear fruit, only grow trees, so in order to avoid overgrowth, we can apply less nitrogen fertilizer, no nitrogen fertilizer during topdressing, and apply more phosphorus and potassium fertilizer to enhance branch growth.

two。 Adult tree

The base fertilizer is applied in the dormant period after autumn harvest, and the tree nutrition is replenished in time after harvest to avoid tree weakness, heat preservation and frostbite, and then prepare for new fruiting branches in the coming year. Therefore, about a week after harvest, it is necessary to apply some quick-acting chemical fertilizer to restore the tree potential, and then apply farm manure. Generally, the combined application of 200 jin of chemical fertilizer and 400 jin of farm fertilizer per mu can ensure a lasting fertilizer effect. The method of strip application can be used to save manpower and material resources, but hole application and ring ditch application are the most favorable for absorption.

Topdressing is the first time in the flowering stage, which requires a lot of nutrition, so it is necessary to apply a lot of compound fertilizer to promote flowering. The second time in the fruit expansion period, when the rapid growth, fertilizer and water supply, mainly phosphorus and potassium fertilizer, less nitrogen fertilizer. In addition, trace fertilizers such as calcium, magnesium and zinc are applied outside the root.

Nectarine fertilization is to separate the fruit trees of different ages and use different amounts of fertilizer according to different periods. So the above is the nectarine tree fertilization process, there are certain targeted fertilization, I hope people with planting needs can help.
