Description
Technical Field
The invention relates to the technical field of pear tree planting control, in particular to a method for controlling pear tree root rot.
Background
The stream is the village of snow pears, the cultivation area of the whole county is 15 ten thousand mu, and the stream is one of leading industries for increasing income of the masses. In recent years, due to the fact that a great amount of chemical fertilizers and pesticides are used, soil hardening or severe acidification is caused, and the occurrence frequency of pear root rot is increased; along with the push of soil improvement projects, land blocks are continuously leveled, the drainage speed is low, the continuous planting garden is gradually enlarged, the disease causes and ways of pear root rot are increased, particularly, the disease rate of the soil pear root rot with yellow mud property reaches more than 20%, and the pear trees cannot be planted in the original place within 3 years after the pear trees with root rot disease die. In conclusion, the research on the control measures of the pear root rot is imperative.
After the root of the pear tree is infected by germs, the germs can quickly spread to the root neck and spread downwards along the main root, serious disease plants quickly cause the death of the whole plant, and most of the serious disease plants are big trees in the full bearing period, and generally, the time from the disease onset to the death of the whole plant is only 1 year, so a set of feasible method needs to be researched in time to reduce or eliminate the root rot, and the method for preventing and treating the root rot of the pear tree is provided.
Disclosure of Invention
Technical problem to be solved
Aiming at the defects of the prior art, the invention provides a method for preventing and treating the root rot of a pear tree, and mainly aims to solve the problem that the root rot of the pear tree is difficult to treat.
(II) technical scheme
In order to achieve the purpose, the invention provides the following technical scheme:
a method for preventing and treating pear root rot comprises the following steps:
s1: treating soil, if planting is carried out on the old forest, thoroughly removing residual roots in the soil, carrying out local soil replacement, applying more organic fertilizer, carrying out soil disinfection and sterilization treatment, preferably carrying out agricultural cultivation for 2-3 years, and then planting pear trees;
if the pear trees are replanted at the positions where the pear trees are dead, digging a large pit for sterilization, disinfection and soil replacement, mixing lime for disinfection when new soil is backfilled, and applying an organic fertilizer containing fulvic acid or a soil conditioner bacterial fertilizer as much as possible;
s2: reasonably applying fertilizer, normally applying fertilizer to the pear gardens without diseased trees, and deeply applying organic bacterial fertilizer to the pear gardens with diseased trees by adopting a method of bacterial sterilization and bacteriostasis;
s3: timely discovering that concentrated treatment is carried out on pear trees with the root rot symptoms that the growth vigor of plants is reduced, new shoots cannot be taken out or are short, fruits are small, leaves are small and thin, and early yellowing and falling off are realized;
s4: reasonable irrigation, wherein the pear trees are separately irrigated with disease-free pear trees during watering to prevent spreading, and the pear gardens with disease are prevented from being irrigated by heavy water as much as possible, so that the root soaking time is shortened, and the serious imbalance of root and branch growth and the reduction of disease resistance caused by the fact that soil is in a high-humidity high-temperature state for a long time and the root system is anoxic are avoided;
s5: the management is enhanced, the flowers and the fruits are reasonably thinned, and the phenomenon that the root rot spreads due to overlarge fruit bearing capacity and overlow organic matter content in soil in successive years, especially due to insufficient medium trace elements and insufficient nutrition supply is prevented;
s6: the fertilizer and water integrated technology is popularized, a complete irrigation system is used for fertilizing, the irrigation system comprises a water storage tank, a fertilizer preparation tank, a machine room, a water pipeline and a water dropper, fertilizer solution is injected into the irrigation water pipeline under the pressure action of a machine room variable frequency motor, water dissolved with fertilizer is injected into a root zone through a water irrigator, and water and fertilizer are absorbed simultaneously.
Furthermore, in S2, the pear trees are carefully controlled to be watered in the growing season, and drainage measures are taken in the rainy season of the high-temperature rainy period to drain the waterlogging in time so as to delay the development of diseases.
On the basis of the above scheme, in S2, fertilizer cannot be applied in unreasonable formula, especially, single-element or inferior fertilizer cannot be applied in a biased manner, and the fertilizer cannot be applied in an excessive manner.
As a further scheme of the present invention, in the step S3, when a diseased tree is treated, the primary diseased plant is first trenched, blocked and isolated, the diseased tree is subjected to soil digging and root drying in autumn, the diseased tree is scraped and then is coated with bordeaux mixture or lime sulphur mixture for protection, the soil around the diseased root is sterilized, and chemical agents are poured through the diseased root.
Further, in the step S3, after the soil around the diseased root is dug out, the soil is replaced with new soil and is mixed with the root-cleaning regeneration element for backfilling, and the seriously diseased plant is dug out as early as possible, and the residual root is thoroughly cleaned and burnt.
In addition to the above, in S5, in order to prevent hardening during soil management, it is necessary to frequently loosen and ventilate hardened soil.
(III) advantageous effects
Compared with the prior art, the invention provides a method for preventing and treating the root rot of the pear tree, which has the following beneficial effects:
1. by treating the soil, the phenomenon that disease-free roots are directly infected and spread through contact with diseased roots or spread through movement of diseased residues can be avoided.
2. Symptoms of root rot were found for the experiments: the growth vigor of the plants is reduced, new shoots can not be taken out or are short, the fruits are small, the leaves are small and thin, and the yellow trees fall off in early stage, so that the diseased trees can be found in time, the treatment can be carried out in time, and the mutual infection can be prevented.
3. The disease-free pear trees are separately watered, spreading can be prevented, the pear orchard with the disease at the beginning avoids flood irrigation as much as possible, the root soaking time is shortened, the situation that soil is in a high-humidity and high-temperature state for a long time, roots are lack of oxygen, root branches grow seriously and are disordered, the disease resistance is reduced, a waterlogging drainage measure is taken in rainy seasons, and waterlogging is drained in time, so that development of diseases is effectively delayed.
4. Through reasonable measures of flower thinning and fruit thinning, the phenomenon that the root rot spreads due to the fact that fruit bearing capacity is too large in successive years, the content of organic matters in soil is too low, particularly, medium trace elements are insufficient, nutrition supply cannot be kept up with the soil, and the phenomenon that the root rot spreads due to the fact that a fertilizer formula is unreasonable, particularly, a single element or an inferior fertilizer is applied partially cannot be excessive during fertilization control, and the phenomenon that the root rot occurs due to the fact that soil is hardened or acidized seriously can be reduced.
5. When the diseased trees are treated, the primary diseased plants are firstly ditched, sealed and isolated, the diseased trees are subjected to soil digging and root drying in autumn, the diseased trees are scraped and then coated with Bordeaux mixture or lime sulphur mixture liquid for protection, the soil around the diseased roots is disinfected, chemical agents are poured into the roots, the soil around the diseased roots is dug out, new soil is changed and mixed with rooting-cleaning regenerant for backfilling, the diseased trees are dug out as early as possible, residual roots are thoroughly cleaned and burnt, and root rot can be effectively prevented.
