Abstract

The invention relates to a fruit tree canopy closure disease rescue method, and relates to the technical field of planting. The method comprises the following steps: budding water is irrigated before budding, and budding top dressing is applied at a same time; during a fruiting period, flowers and fruits are thinned, and a protection agent, a fungicide and an insecticide are applied; fertilization is carried out twice in autumn; fruits are bagged; bags are removed, and the fruits are colorized; pruning is carried out in the four seasons, and lime sulfur is applied. With the method provided by the invention, fruit trees with a canopy closure problem can be rejuvenated, and fruit tree canopy closure disease can be effectively solved. With the method, fruit tree full productive period can be maximized; fruit nutrients are comprehensive; fruit taste is good; and fruit farmer economic benefit is improved. The method is convenient, feasible and economical. The method can be implemented by every fruit farmer, and is suitable for large-scale popularization.

Description

The method of suing and labouring of fruit tree " closing disease "

Technical field

The present invention relates to the method for suing and labouring of fruit tree " closing disease ", belong to planting technology field.

Background technology

The planting fruit trees such as apple, pears industry is one of important industry of farmer richness, and fruit tree, through growth for many years, enters the aging stage, tree crown is connected each other, causes closing of space, occurs " closing " phenomenon, have a strong impact on fruit output and planting benefit, directly affects the income of orchard worker.The tree branch of suffering from " closing disease " is thick, and stuffy, light tight, cause fruit head little, sell difference, price does not increase.According to way in the past, veteran to be cut down exactly and to plant new tree, however orchard worker be reluctant to cutting down oneself " cash cow " because new fruit tree will wait 3 to 4 years, just can enter fruiting period and the full bearing period.

At present, scientific research personnel proposes a kind of rejuvenating method of transformation fruit tree " closing ", namely on the original limb basis of reservation, new branch group is cultivated above, allow its result again, so just the branch of some agings can be cut in time, " closing " problem can be solved to a certain extent, extend the full bearing period of fruit tree.But, cultivate that new branch group needs the support of technology, most orchard worker is difficult to carry out, need to spend a large amount of manpower and materials, and cultivation period be longer, for orchard worker adds financial burden, inhibits the income of orchard worker.

Summary of the invention

In order to overcome the defect existed in prior art, the present invention aims to provide a kind of method of suing and labouring facilitating feasible, economical and practical fruit tree " closing disease ".

To achieve these goals, the present invention adopts following technical proposal: the method for suing and labouring of fruit tree " closing disease ", comprises the following steps:

1) before rudiment, fill with rudiment water, and chase after rudiment fertilizer simultaneously;

2) to bear fruit phase flower and fruit thinning, beat protectant, bactericide, insecticide, drug effect reinforcing agent, organosilicon, trace element simultaneously;

3) twice fertilising in autumn;

4) bagging is carried out to fruit;

5) de-bag, painted;

6) four seasons beta pruning, and play lime sulfur.

Step 2) in, described protectant be hundred Thailands, Du Pont, gloomy greatly in the mixture of one or more; Described insecticide is one or both the mixture in killing than worm spirit, essence; Described trace element is fertile raw L116.

In step 3), institute's fertilise contains silicon, calcium, magnesium, nitrogen, phosphorus, potassium composition, and fertilizing amount and fertilizing method are: the soil around every fruit tree is affixed by soil conditioner, Si, Ca, Mg, K fertilizer 500 ~ 750g, nitrogen, phosphorus, the potassium fertilizer 1000g of 500g blue sky board; Every mu of soil is executed and is spilt biofermentation farmyard manure 2 tons.

In step 6), every tree cuts 70% branch, allows light air circulation, guarantee lead to light and ventilates.

Compared with the prior art, the present invention, owing to have employed technique scheme, impels the fruit tree of " closing " to radiate the vigour of youth, effective releasing fruit tree " closing disease ", extend the full bearing period of fruit tree to greatest extent, fruit nutritive element is comprehensive, mouthfeel is good, improves the economic well-being of workers and staff of orchard worker; It facilitates feasible, economical and practical, and each orchard worker can implement, and suitable large area is promoted.

Embodiment

Below in conjunction with specific embodiment, the invention will be further described:

Embodiment 1, the method for suing and labouring of fruit tree " closing disease ", comprises the following steps:

2) to bear fruit phase flower and fruit thinning, make a call to simultaneously hundred safe, than worm spirit, bactericide, drug effect reinforcing agent, organosilicon, fertilely give birth to L116;

3) twice fertilising in autumn, its method is soil conditioner, Si, Ca, Mg, K fertilizer 500 ~ 750g, nitrogen, phosphorus, the potassium fertilizer 1000g that soil around every fruit tree is affixed by 500g blue sky board; Every mu of soil is executed and is spilt biofermentation farmyard manure 2 tons;

4) bagging is carried out to fruit;

5) de-bag, painted;

6) four seasons cut 70% branch, allow light air circulation, guarantee lead to light and ventilate, and play lime sulfur.

King so-and-so, its orchard area is more than 20 mus, all plants apple tree, annual is all fertilising in winter, and born fruit 17 years, recent five years output has the trend of downslide, fruit tree presents " closing ", and last year, it adopted the method described in embodiment 1 to sue and labour, and autumn applies fertilizer, every tree four seasons cut 70% branch altogether, allow light air circulation, guarantee lead to light ventilate, fruit tree is radiated the vigour of youth, grow fine, output obviously increases.
