Abstract

The present invention relates to a kind of pear tree fertilizing methods, specifically includes the following steps: one) fertilization principle；Two) fertilizing method and dosage: 1) base manure, 2) soil topdressing, 3) foliage application, 4) facility fertilising, nutritional ingredient needed for this method can guarantee Growth of Pear Trees obtains abundant, reasonable supplement, facilitate Growth of Pear Trees, bloom and result, fruit-setting rate and fruit tree quality are improved, there is good promotional value.

Description

A kind of pear tree fertilizing method

Technical field

The present invention relates to field of fruit tree cultivation, and in particular to a kind of pear tree fertilizing method.

Background technique

The fertilising of fruit tree occupies important function in fruit tree growth, if dose, fertilization time and fertilizing method control It is bad, it will have an adverse effect to the growth of pear tree, the final percentage of fertile fruit and fruit quality for influencing fruit tree.

Summary of the invention

To solve the above-mentioned problems, the invention proposes a kind of pear tree fertilizing method, can guarantee needed for Growth of Pear Trees Nutritional ingredient obtains abundant, reasonable supplement, facilitates Growth of Pear Trees, blooms and as a result, improving fruit-setting rate and fruit tree quality, have Good promotional value.

The present invention is achieved by the following technical solutions: a kind of pear tree fertilizing method, specifically includes the following steps:

One) fertilization principle, pear tree normal outcome need nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, iron, manganese, boron, zinc, copper, molybdenum, chlorine, 14 kinds of tweezer must the beneficial elements such as mineral element and silicon；Childhood and first fruiting period tree, it should be noted that suitable control nitrogen, suitably increase phosphorus Fertilizer, the nitrogenous fertilizer, phosphate fertilizer, potash fertilizer are supplied in 1: 2: 1 ratio；Best fruiting period pear tree needs potassium amount to dramatically increase, every production double centner fruit Real, pear tree about needs to absorb 0.55 kilogram of nitrogen, 0.27 kilogram of phosphorus, 0.68 kilogram of potassium, and when fertilising can refer to above data.

Two) fertilizing method and dosage, 1) base manure: autumn 9, October apply, and based on farmyard manure, mix a small amount of chemical fertilizer, Dose applies 2~4 kilograms of high-quality farmyard manures by 1 kilogram of the operatic circle, and method of administration is based on ditch spread, and position of applying fertilizer is in crown mapping model In enclosing；2) soil topdressing: number, time, dosage of top dressing etc. are according to kind, the age of tree, growth and development period and external condition Deng and different, the fruit development period phase of earsh and bearing-age tree, top dressing is based on nitrogenous fertilizer, and the fruit development later period is with phosphorus potash fertilizer Based on；3) foliage application: annual 7~8 times, growth early period 2 times, based on nitrogenous fertilizer, the later period 4~5 times, based on phosphorus potash fertilizer, together When, implement fruit tree microelement needed for growth and development；4) facility applies fertilizer: production because of planting density and the relationship of overlay film, in By 150 kilograms of Gao Jia type compound fertilizer, 7000~9000 kilograms of high-quality farmyard manure and 150~250 kilogram one of bean flour per acre after fallen leaves Secondary property applies, and the feature big according to Growth of Pear Trees nitrogenous fertilizer early period expense, it is proposed that takes the circumstances into consideration to spread fertilizer over the fields to early October in late August Or 35,000 grams/acre of urine is applied in cave, to increase the accumulation of tree body nitrogen, prevents young fruit because of nitrogen deficiency shedding；The fruit stone later period is every Mu imposes 150 kilograms of bean flour, 25~30 kilograms of Gao Jia type compound fertilizer, to guarantee that fruit sufficiently expands.

The beneficial effects of the present invention are: a kind of pear tree fertilizing method, nutritional ingredient needed for capable of guaranteeing Growth of Pear Trees obtain To abundant, reasonable supplement, facilitates Growth of Pear Trees, blooms and as a result, improving fruit-setting rate and fruit tree quality, have and promote well Value.

Specific embodiment

Below with reference to embodiment, the invention will be further described.

Embodiment 1

A kind of fertilizer practice for open country pear tree, Pear Trees with Various Cultivars are the wonderful spring, specifically includes the following steps:

Two) fertilizing method and dosage, 1) base manure: autumn 9, October apply, and based on farmyard manure, mix a small amount of chemical fertilizer, Dose applies 2 kilograms of high-quality farmyard manures by 1 kilogram of the operatic circle, and method of administration is based on ditch spread, and position of applying fertilizer is in crown mapping range It is interior；2) soil topdressing: number, time, dosage of top dressing etc. are according to kind, the age of tree, growth and development period and external condition etc. And different, the fruit development period phase of earsh and bearing-age tree, based on nitrogenous fertilizer, the fruit development later period is with phosphorus potash fertilizer for top dressing It is main；3) foliage application: annual 5 times, growth early period 2 times, based on nitrogenous fertilizer, the later period 3 times, based on phosphorus potash fertilizer, meanwhile, Shi Guoshi Set microelement needed for growth and development.

Embodiment 2

A kind of fertilizer practice for open country pear tree, Pear Trees with Various Cultivars are middle avocado 14, are cultivated, are specifically included using greenhouse Following steps:

One) fertilization principle, pear tree normal outcome need nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, iron, manganese, boron, zinc, copper, molybdenum, chlorine, 14 kinds of tweezer must the beneficial elements such as mineral element and silicon；Childhood and first fruiting period tree, it should be noted that suitable control nitrogen, suitably increase phosphorus Fertilizer, the nitrogenous fertilizer, phosphate fertilizer, potash fertilizer are supplied in 1: 1: 1 ratio；Best fruiting period pear tree needs potassium amount to dramatically increase, every production double centner fruit Real, pear tree about needs to absorb 0.46 kilogram of nitrogen, 0.29 kilogram of phosphorus, 0.74 kilogram of potassium, and when fertilising can refer to above data.

Two) fertilizing method and dosage, facility pears are produced because of planting density and the relationship of overlay film, by every generally after fallen leaves 150 kilograms of Mu Gaojia type compound fertilizer, 7500 kilograms of high-quality farmyard manure and 200 kilograms of bean flour disposable applications, and it is raw according to pear tree The big feature of long nitrogenous fertilizer early period expense, it is proposed that take the circumstances into consideration to spread fertilizer over the fields in late August to early October or cave applies 15,000 grams/acre of urea, To increase the accumulation of tree body nitrogen, prevent young fruit because of nitrogen deficiency shedding；The fruit stone later period impose per acre 150 kilograms of bean flour, 25 kilograms of Gao Jia type compound fertilizer, to guarantee that fruit sufficiently expands.
