Can lime be sprinkled on watermelon leaves?

Lime can not be sprinkled directly on the watermelon leaves, otherwise it will burn the leaves, it is recommended to sprinkle it in the watermelon field.

In addition, there are many pests, pest eggs, and bacteria lurking in the soil, and some pests and bacteria will be transmitted to the watermelon plants, especially in the fields where watermelons have been planted on the stubble, and the remaining pests and diseases will seriously threaten the watermelon plants with stubble. In order to solve these residual pests and diseases, lime is needed to kill insects.

Lime used in acidic soil environment is helpful to increase the yield of watermelon, but lime because of its high alkalinity, long-term use will aggravate the degree of soil alkalinity, in addition to the insecticidal ability of lime is too strong, will accidentally kill most of the beneficial organisms in the soil (earthworms, resulting in the lack of beneficial bacteria in the soil, affecting the degradation of chemical fertilizer salt substances and organic matter, resulting in poor soil fertility, this should be taken into account when using lime to improve the soil.

Personally, it is recommended that watermelon farmers also disinfect the soil once when neutralizing the acidity of the soil to prevent soil-borne diseases from infecting watermelons, although quicklime.

It will kill most of the beneficial organisms, but these beneficial organisms can be supplemented by increasing organic fertilizer.

Before watermelon planting, water is diverted from the field, and then quicklime is sprinkled, and the quicklime begins to decompose after entering the water, and a large amount of heat will be generated during the decomposition process to kill underground pests and latent germs, and even burn the roots and seeds of weeds, reducing the amount of weeds in the field in the future; The application of quicklime in the field can also play a role in making farmhouse fertilizer, which can speed up the decay of unrotten weeds and straw grass in the field.

Note: Lime is used in watermelon planting land, and the amount of lime per mu per year cannot exceed 300 catties, and the continuous use of lime should not exceed 2 years.

Definitely not! If there are insects, you can sprinkle plant ash (that is, the ashes of cooking with a wood stove) on the watermelon leaves, and the insects will be destroyed, and it will have no effect on the watermelon leaves. Very good, this is the insecticidal method used by the elderly in the family to farm in the past!

Although watermelon is more adaptable to the soil, it is very susceptible to disease and wilt in acidic soil. Watermelon wilt disease is a common disease on watermelon, mainly harming the roots of watermelon, and will occur in the entire growth period of watermelon, which is extremely harmful, and can cause the extinction of watermelon in serious cases.

Watermelon wilt is mainly due to continuous cropping, and the soil is acidic, which is conducive to the survival and reproduction of Fusarium wilt, which leads to the occurrence of Fusarium wilt.

Adjusting the acidity of the soil can be improved by sprinkling quicklime.

Quicklime is calcium oxide, after being applied to the soil, it combines with water to form alkaline calcium hydroxide, and at the same time generates a large amount of heat, which can kill soil pests and bacteria, and can supplement the calcium element of the soil.

However, sprinkling of quicklime on the soil is not an innumerable process. Use too little, can not play the role of quicklime, the amount of use is too large, and will cause the alkalinity of the soil, press down the gourd to scoop, and then adjust the alkalinity? As people say, if there is more noodles, add water, and if there is more water, add noodles?

The best way to sprinkle quicklime on the soil is to test the pH value of the soil, and then decide the amount of quicklime to sprinkle per mu according to the advice of professionals.

It will definitely burn out the leaves. Why use lime, sterilization should be done with fungicides.

Before planting watermelons, water is diverted from the field and then quicklime is sprayed. Quicklime begins to decompose when it enters the water. During the decomposition process, a lot of heat is generated, killing underground pests and latent bacteria, and even burning the roots and seeds of weeds to reduce the number of weeds in the field in the future; The application of quicklime in the field can also act as a degumming farmhouse fertilizer, accelerating the decay of unrotten weeds and straw in the field.

When the soil is acidic, we can still sprinkle quicklime into the soil a month before the watermelon is planted. Quicklime is alkaline. Sprinkle quicklime in acidic soil, neutralize the soil, and make the soil weakly acidic.

Effectively reduce soil-borne diseases and pests of watermelon; It is essential for the growth of watermelon. This is very helpful in improving the quality of watermelon. Lemons should not be sprinkled directly on the leaves of watermelon, otherwise they will burn the leaves.

It is recommended to sprinkle on watermelon grounds. There are many pests lurking in the soil. Some pests and bacteria can infect watermelon plants, especially in fields where watermelons are planted in the last season.

Residual pests and diseases will seriously threaten the continuous cropping of watermelon. In order to eradicate these residual pests and diseases, the insects need to be killed and disinfected with quicklime.

The application of lime in an acidic soil environment can help increase watermelon yields, but long-term application of lime will exacerbate soil alkalinity due to its high alkalinity. In addition, lime has a strong insecticidal and sterilizing ability, which will accidentally kill most of the beneficial organisms in the soil, resulting in a lack of beneficial bacteria in the soil, affecting the degradation of chemical fertilizers, salts and organic matter, and resulting in poor soil fertility. When using lime to improve the soil, it is recommended that watermelon growers should also disinfect the soil when neutralizing the acidity of the soil to prevent soil-borne infection.

While quicklime kills most beneficial organisms, increasing the application of organic fertilizers can supplement these beneficial organisms. Lime is used in watermelon growing fields. The annual amount of lime per mu shall not exceed 300 kg, and the continuous use of lime shall not exceed 2 years.

It is very suitable, quicklime can play a role in disinfection and sterilization, can remove some bacteria in the land, can increase the nutrition of the soil, and is more conducive to the planting and growth of watermelon.

It is particularly suitable, but if you want to sprinkle quicklime, be sure to sprinkle it in the previous month, it can kill the bacteria in the ground and promote the growth of watermelons.

Very suitable, quicklime can neutralize the pH of the soil, and the value improves the soil for the growth of crops.

Summary. Good afternoon, dear, glad to answer for you; "Yes, you can. Hydrated lime is also known as slaked lime.

It is made by quicklime when it is added to water or when it is stacked, and a large amount of heat is released when it absorbs water. The main component of hydrated lime is calcium hydroxide, with a calcium content of about 70%. Hydrated lime is alkaline and has a weaker ability to neutralize soil acidity than quicklime.

It also has the effect of killing soil pests, weeds and soil disinfection. In the cultivation of watermelon seedlings in Jingxin, hydrated lime can be used as base fertilizer and top dressing, but not as seed fertilizer. Spread evenly to prevent local soil from being too alkaline or not being applied.

It should not be applied continuously and in large quantities.

Good afternoon, I have checked your questions, and I am inquiring for you, please wait a while, don't end the consultation immediately!

Watermelon is adaptable to soil, but it is prone to disease, wilting, and disease in acidic soil. Watermelon wilt is a common disease of watermelon, which mainly harms the roots of watermelon, and the disease occurs during the growth period of watermelon, which is very harmful and may lead to a reduction in watermelon yield. Watermelon wilt is mainly continuous cropping, and the soil is acidic, which is conducive to the survival and mass reproduction of Fusarium wilt, resulting in the occurrence of Fusarium wilt.

Quicklime is calcium oxide, which is applied to the soil and combined with water to produce alkaline calcium hydroxide, and at the same time produces a lot of heat, which can kill soil pests and bacteria, and replenish the calcium in the soil.

But spraying quicklime on the soil is not an endless progress. The use of too little can not play a legitimate role in quicklime, too much use will lead to soil alkalinity, according to the gourd silk scoop, adjust the alkalinity? Are you saying, as people say, "put a lot of water on the noodles, and put a lot of water on the water"?

The best way to spray the soil with quicklime is to test the pH of the soil and then, on the advice of experts, determine the amount of quicklime to be sprayed according to the grave. For the adjustment of soil acidity and alkalinity, it can be adjusted by organic fertilizer certificate, calcium, magnesium, phosphate fertilizer and other alkaline fertilizer certificate, and less application of fertilizer with high sulfur content.

The prevention and control of watermelon, wilt and other soil diseases should be strictly implemented in rotation, and second, varieties with strong disease resistance should be selected, as mentioned above, using organic fertilizer certificates, quicklime adjustment, etc. Moreover, it is best to properly dispose of fruit wine, diseased leaves, peels, etc., and do not feed the peels to pigs. Pig manure is also one of the main sources of infection such as wilted germs, and it is necessary to strictly use drugs before use, and finally use drugs to prevent soaking, spraying or irrigation.

To be precise, sulfur powder is a soil amendment. Adding sulfur powder to the soil has the effect of reducing pH, making the soil acidic, killing insects and sterilization, and increasing the sulfur content of the soil. Adding too much sulfur powder can damage the biological activity of the soil, so there are not many sulfur powders used in planting to improve the soil.

The cultivation of fruit trees and flowers is rarely used for vegetables and cultivation. We have been growing vegetables in plastic greenhouses for more than 10 years, and we have not improved the soil with sulfur powder. Studies have shown that if one unit of pH needs to be reduced, about 80 kilograms of sulfur powder should be added per acre.

The method of adding sulfur powder is to spray it evenly and then turn the soil deeply by more than 20 cm. After sprinkling sulfur powder, it takes about 6 months to 1 year to reduce the pH of the soil. The effect can only last for about 3 years, and sulfur powder needs to be added.

However, if sulfur powder is added repeatedly, it will reduce the activity of soil enzymes, the number and variety of soil microorganisms, and deteriorate the soil environment.

Simply adding this chemical is not effective in improving soil pH. More and more of our growers are adding organic fertilizers to regulate the pH of the soil (such as charcoal, pine needles, wood chips, bark, etc.). While adjusting the soil pH, the soil organic matter content is increased, so that the soil is fertile, which is more conducive to crop growth.

I think sprinkling lime can change the acidity of the soil, so that the watermelon can fully absorb the nutrients of the soil, so I think it can promote the high yield of watermelon.

It is to protect the roots of watermelons from being harmed while growing. OK.

The main purpose of sprinkling lime is to increase the air permeability of the soil and prevent compaction in the watermelon soil. Moreover, lime is also rich in nutrients, which can promote the growth of plant rhizomes, and sprinkling lime can promote the high yield of watermelon.

It can not only help sterilization and disinfection, but also help adjust the acidity and alkalinity of the soil, and can also help improve the yield.

Because lime contains a lot of minerals that plants need to grow, and supplementing these minerals can promote some high yields.

On the issue of sprinkling quicklime in the field, some friends have done this, but most of them are estimated not to have done this, occasionally I heard others say that sprinkling quicklime in the field is beneficial, but because I don't know what its specific role is, I didn't dare to try, below, the little helper will talk about his own views on the matter of sprinkling quicklime in the field.

1. Improve soil acidity.

Because most of the pesticides are acidic, so the problem of soil acidification needs to get more and more attention from us, some of the soil with serious acidification, can not grow crops at all, at this time, you can use quicklime to neutralize the pH value, improve the soil, is conducive to the normal growth of crops.

2. Soil sterilization.

The heat generated by quicklime during the maturation process can kill the germs in the soil, such as common soil-borne diseases.

3. Anti-insect effect.

Insect control also relies on the heat generated by quicklime maturation to destroy insect eggs in the soil and reduce the number of insect infestations.

4. Increase crop yield.

After neutralizing the acidic soil, the soil reaches a normal value, which is conducive to the decomposition of beneficial microorganisms in the soil, in this case, the nutrients needed for the growth of the crop, in addition to external application, can also be provided by itself, which helps to increase the final yield.

In addition to the above 4 benefits, quicklime should be sprinkled into the field, and some 3 aspects should be paid attention to:

1. Not all fields can be sprinkled with quicklime, under normal circumstances, only the soil is acidic plots can be used, if the pH is exceeded, it can no longer be used (there is a professional pH measurement machine, friends who want to use it can test it in advance).

2. In terms of dosage, weak acid and acidification of more serious plots, the amount of use is not the same, the little helper remembers to see a data, weak acid plots, about 100 catties per mu is about the same, serious acidification plots, can be 200-300 catties (this amount is only approximate, specific, but also according to the specific situation of the soil specific analysis), in the case of excessive application, resulting in high soil alkalinity, then the gains outweigh the losses.

3. When applying quicklime, do not use it if it contains impurities or agglomerates, and it is recommended to buy it now.
