What to do if iron fertilizer causes pesticide damage to kiwifruit fruits

At present, it is known that kiwifruit is very sensitive to a variety of agents such as dimethoate, dimethoate, thiophos, mancozeb, thiophanate-methyl, glyphosate, simazine, Tectin, 2,4d and so on, and should be used with caution or prohibited.

1) Dimethoate is best forbidden on kiwifruit, especially early spraying, due to the deformity of young leaves can not stretch normally, the branches can not grow normally, the young buds fall off, the germination rate is reduced, the growth is seriously hindered, resulting in reduced yield, at the same time, due to the obvious small and deformed leaves, the photosynthetic function is seriously hindered, and the root system can not get enough photosynthetic products and "starve" to death.

2) Glyphosate injures young kiwifruit trees, resulting in over-elongation and deformity of leaves, upward uplift of interveined tissues, and sometimes green fading of damaged leaves. Adult trees are much more resistant to pesticides, and the symptoms of damage first appear on the young leaves, which are bright yellow and green, which starts from the leaf margin, expands between the leaf veins and expands to the main vein, and retains healthy green tissue on both sides of the main vein.

3) 2,4d injury can cause leaf deformity in kiwifruit, and the leaf margin rolls up or down into a saucer, which has a significant impact on the leaf size, and often causes the intervein tissue to bulge upward. The infested leaves do not fade green. Plants damaged by pesticides for 2,4 days in autumn produce deformed leaves and fruits in the next season.

The deformed fruit is characterized by a sharp cut towards the umbilicus, a depression in the umbilicus, and a slight longitudinal convex line.

Kiwifruit is sensitive to pesticides and must be tested before using pesticides, herbicides, and hormones.

To test the optimal spraying concentration of iron fertilizer on kiwifruit fruit.

Summary. Dear, I'm glad to answer for you, what is the remedy for kiwifruit fertilizer, which can be remedied in this way: measures to prevent fertilizer damage (1) control the total amount of fertilizer, formula fertilization, and the total nitrogen per mu throughout the year does not exceed 35 kg of pure nitrogen.

2) Pay attention to the application of organic fertilizer: in September in autumn (or 10 days after fruit picking) apply no more than 3500 kg of decomposed organic fertilizer, and add biological agents, multi-mineral fertilizers and 60% of the year's chemical fertilizers. (3) During the critical period, the suitable topdressing is mainly chemical fertilizer, and it is applied when there are leaves on the shelf surface to maximize the fertilizer effect.

At the same time, the application of chemical fertilizers, mastery: sprinkling, moisture is good before and after application, after germination, nitrogen fertilizer is the mainstay, and compound fertilizer is applied.

(2) Pay attention to the application of organic fertilizer

In autumn in September (or 10 days after fruit picking), no more than 3500 kg of mu's decomposed organic fertilizer is applied, and biological agents, multi-mineral fertilizers and 60% of the year's chemical fertilizers are added. (3) In the critical auspicious period, topdressing is suitable for topdressing, and topdressing is mainly based on chemical fertilizer, and it is applied when there are leaves on the shelf surface to maximize the fertilizer effect. At the same time, the application of chemical fertilizers, mastery:

Sprinkle and moisture is good before and after application, and after germination, nitrogen fertilizer is the main application, and compound fertilizer is applied.

Rescue measures after fertilizer damage A large amount of water is irrigated, and excessive fertilizer is washed and divided into the lower layer. Foliar spraying of brassin, bihu, and meijiafu promotes tree recovery. Irrigate the roots of the branches with a rooting agent that leads the way, or wash it with water, and let you lead the way.

The crack in the trunk was painted in time to smear Qi and slaughter. After a month, if it does not heal, the crack is smeared with a whisk gram. After the fertilizer damage occurs, the grass is temporarily left to allow the grass to consume fertilizer.

When the grass is too high, it is mowed, covered with tree trays, and decomposed to become organic fertilizer.

I already have fat damage how to remedy it.

Hello dear <> my answer is as follows, please be patient and take a look at the <>

Here are some things you can do to remedy this:1Handling of soil:

Add an appropriate amount of organic fertilizer and compound fertilizer to the kiwifruit planting ground to promote the organic matter content and fertility of the soil, and at the same time increase the acidity of the soil to prevent the negative impact of soil too alkaline on plants. 2.Dealing with pests and diseases:

For different pests and diseases, it can be sprayed with appropriate chemicals, natural plant extracts or microbial preparations. Before carrying out these treatments, it is necessary to understand the norms for the use of drugs and the guidance of the lack of safety and safety, as well as the environmental and health hazards caused by the use of drugs. 3.

Adjust the growing environment: Adapt to change the cultivation environment, control temperature, humidity, light and ventilation to help kiwifruit grow and adjust mood. 4.

Switching varieties: If the kiwifruit has been severely damaged by fertilizer for a long time and the growth situation is not ideal, you can also consider changing the kiwifruit variety that is more suitable for local cultivation.

Summary. Hello dear! We're happy to answer for you!

Generally, for kiwifruit fruit trees that have been fertilized, the main remedies are as follows: irrigation and dilution. Improper soil fertilization causes fertilizer damage, and should be immediately watered with large water to dilute the fertilizer concentration.

Plough the soil. If the amount of fertilizer is too large, the water source conditions are insufficient, or the soil clay weight is poorly infiltrated, the soil can be ploughed to control water and fertilizer to reduce fertilizer damage. If the roots have been severely damaged, the soil around the underground part of the plant should be cleared and the roots should be dried for a short period of time to promote the growth of new roots.

<> pro, and then dig out the backfill. Dig out the fertile soil in the fertilization ditch and pile it outside the ditch, and then backfill a part of the fertile soil at intervals (10 15 days), and backfill it in several times. Root Breaking Method.

For orchards with heavier fertilizer damage and less labor force in Changqi, the root cutting method has a better effect, that is, cutting the large roots that are resistant to sale such as broken burns along the inner side of the fertilization ditch, and digging out the backfill topsoil. <>

<> and remedial measures: If the person has been damaged by the disorder, the cause of the collapse should be investigated, and corresponding remedial measures should be taken in time to minimize the damage. For fertilizer damage caused by improper fertilization, it should be irrigated with large water immediately to dilute the fertilizer concentration.

If the roots have been seriously injured, the soil at the fertilization site should be dug up, the root system that has been dead should be cut off, the roots should be dried for a short time, and the soil should be backfilled for about 10 days. <>

<> pro-middle staring, [slight rolling laughter] kiwifruit fertilizer and pesticide damage often cause leaves to be sold and burned, and the leaves are browned, blackened, burnt yellow, dry and fall off. Therefore, it is necessary to apply medicines and fertilizers correctly, prepare them in strict accordance with the instructions, and do not increase the concentration at will. For example, with the application of the water-soluble fertilizer of the Cerfert series, as long as it is diluted according to the following multiples, there will be no problems.

At the same time, it is necessary to avoid medication during high temperature periods. <>

<> relatives, if pesticide damage and fertilizer damage are found, the following measures can be taken in time: When the leaves and plants are seriously damaged, they should be irrigated in time to loosen the soil by cultivating and cultivating to promote the development of the root system and enhance the ability of the plant to recover and slow down; If the pesticide is misused or the concentration of the pesticide is too large, a large amount of water should be sprayed immediately to wash the plant, and it can also be sprayed for rescue; If the soil fertilizer is not used properly, it is necessary to carry out field drainage and irrigation fertilizer to reduce the fertilizer concentration. <>

Summary. Fill with a lot of water, drench too much fertilizer and divide it into the lower layer. Foliar spraying of brassin, bihu, and meijiafu promotes tree recovery.

Irrigate the roots with a rooting agent that leads the way with you or apply it with water. The cracks in the trunk are smeared and slaughtered in time. After a month, if it does not heal, the crack is smeared with a whisk gram.

After the fertilizer damage occurs, the grass is temporarily left to allow the grass to consume fertilizer. When the grass is too high, it is mowed, covered with tree trays, and decomposed to become organic fertilizer. Replace excess inorganic fertilizer with organic fertilizer and slowly return it to the soil and plants.

If there is room for development on weak trees, but the branches are capped, remove the top leaves and leave the stalks, and after a period of time, dip the top bud growth point into the branch treasure, so that there are more leaves, and make full use of the fertilizer.

Summary. Dear, I am glad to answer for you: Can you spray foliar fertilizer with iron fertilizer for young kiwifruit fruits: Can you spray young fruits with iron fertilizer Oh kiss helps to improve nutrient supply.

Dear, I am glad to answer for you: Can young kiwifruit fruit with iron fertilizer be sprayed with silver foliar fertilizer: young fruits can be sprayed Oh kiss helps to improve nutrition for Shitong to give Oh kiss.

Targeted selection of foliar fertilizer types. When selecting foliar fertilizer, the possible deficiency should be comprehensively judged according to the growth status of kiwifruit, soil acidity and alkalinity, root fertilization type and fertilizer amount and other factors, so as to determine the seed and amount of foliar fertilizer, such as iron deficiency yellow leaves, new leaves spoon-shaped leaves caused by calcium deficiency, small leaf yellow leaves caused by zinc deficiency, amino acid chelated elemental iron, calcium, zinc, etc.; In the flower bud differentiation stage, boron fertilizer and phosphorus supplementation should be emphatically sprayed. For the tree weakness caused by insufficient root fertilization, the early forest can choose to use foliar fertilizer with nitrogen, phosphorus and potassium as the main components; In the event of low temperature, high temperature or drought, it is advisable to choose animal-derived amino acid fertilizers that can significantly enhance stress resistance. In the swelling period of young kiwifruit in spring, there is a huge demand for nutrients, and foliar spraying of full-nutrient foliar fertilizer containing large, medium and trace elements can supplement nutrients in time and make up for the lack of nutrient supply at the roots.

Will it contaminate the fruit surface?

Normal use is not polluting, kiss and spray evenly.

Every year, the rapid expansion of young kiwifruit fruit in late May to late June is the high incidence of fertilizer damage, the fruit farmers are reminded to be sure to apply fertilizer scientifically and beware of fertilizer damage, the following ** is the performance of serious fertilizer damage after 3-5 days.

The rapid expansion period of young fruit is the period of sharp rise in temperature, the summer high temperature period of a year follows, the leaf transpiration is vigorous, the root system is very sensitive to the concentration of soil solution, and this period is the application period of promoting fruit fertilizer and fruit fertilizer, and it is also the peak period of leaf spot disease, therefore, it is very easy to occur high temperature and heat damage, leaf spot disease, fertilization and fertilizer damage, and most of the cases are comprehensive occurrence (mixed hair), it is difficult to identify which kind of "harm", which brings difficulties to diagnosis and treatment, and often causes great losses.

Among them, the most problematic is man-made fertilizer. Due to the large amount of fertilizer applied at one time (more than 1 kg per plant), concentrated fertilization, too close to the root system, and the application of fake and shoddy fertilizers, fertilizer damage may occur, and the damage to the root system is mostly irreversible.

To avoid the occurrence of fertilizer damage, summarize in three sentences: master the principle of far dispersion, use a small amount many times, and choose assured fertilizer.

Yesterday in Qishan Qinghua Town Wei Jianhua this year newly planted kiwifruit orchard found part of the yellowing tree, in order to explore the internal causes of yellowing trees, the site excavated roots, through a yellowing and another normal seedling digging root comparison, it is obvious that the yellowing seedlings are at least 10 cm deeper than the normal seedling planting depth, and the previous in the martial arts base ** yellowing causes are very similar, further verification, for the planting seedlings yellowing wishes, the main yellowing cause is deep-rooted yellowing.

In the past, I have summarized the following inducing factors of kiwifruit yellowing, one is alkaline yellowing, the second is deep-rooted yellowing, the third is weak yellowing, the fourth is overload yellowing, the fifth is fertilizer yellowing, the sixth is water yellowing, the seventh is climate yellowing, and the eighth is phenological yellowing. From the present point of view, deep-rooted yellowing is the most common cause of all yellowing, or all other yellowing factors will only occur yellowing under the premise of deep roots.

A large number of survey examples have proved this law, in addition, from the requirements of kiwifruit biological habits on soil (HP) value, soil type, and soil texture, once planted too deeply, all growth obstacles, including yellowing, will appear one after another, so it can be said that the real lure of kiwifruit yellowing is deep roots, artificially planted too deep. I wonder if my peers agree with me?
