During the planting of garlic, the temperature is high, and the garlic seedlings grow vigorously, ho

First of all, you should protect the temperature of the garlic seedlings, and you can cover them with a layer of thermal insulation film, which will be better.

The growth problems of garlic in the planting process are mainly due to the lack of nutrients such as nitrogen, phosphorus, potassium, etc., which makes the growth and development of garlic stunted, the stress resistance decreases, and the growth potential is weakened. or the use of too much chemical fertilizer, resulting in the increasing salt content of the soil, aggravating the salinization of the soil, weakening the water and fertilizer absorption capacity of the garlic root system, and then affecting the growth of garlic; Garlic planting is easy to dwarf plants, which affects the yield! How should farmers respond? Therefore, in order to avoid the dwarfing of garlic in the planting process, we should pay attention to reasonable fertilization, and at the same time, in the specific process of planting, we should also pay attention to the prevention and control of diseases.

When sowing, we can evenly sprinkle 3% phosphine granules kilogram mu or 15% chlorpyrifos granules kilogram mu on the ground, plow into the soil, and then sow seeds; Of course, if possible, it is best to constantly change the planting land according to the growth cycle of garlic and continuously improve the quality of garlic seeds. In this way, there is a certain rejuvenation effect, and the greater the difference, the better the effect; Pests and diseases of garlic have been planted for many years, and the seedlings have weak resistance and are susceptible to diseases. For example, root-knot nematodes multiply in the soil year by year, destroying the root system of garlic, affecting the normal development of garlic, and causing the plant to be short.

Nutrient-deficient garlic needs to be supplemented with nitrogen, phosphorus, and potassium in production.

Failure to pay attention to the application of organic fertilizer and medium and trace element fertilizer will inevitably lead to the imbalance of the proportion of nutrients required by garlic, resulting in poor growth and development of garlic, decreased stress resistance, weakened growth potential, and physiological diseases of nutritional deficiency. Excessive application of chemical fertilizers in the soil leads to the increasing salt content of the soil, which aggravates the salinization of the soil and weakens the water and fertilizer absorption capacity of the garlic root system, thereby affecting the growth of garlic. In addition, mechanical pressing, plastic film mulching, frequent irrigation and perennial rotary tillage make the soil compact, resulting in soil structure damage, poor air permeability, affecting the growth of garlic and resulting in dwarf plants.

How to prevent garlic sprouts from being short? Garlic seed selectionWhen choosing garlic seeds, try to choose garlic cloves with large garlic cloves, fresh color, no scars, no pests and diseases, and no peeling as seed garlic.

Planting managementIn the process of planting garlic, it can be divided into wet sowing or dry sowing. Under normal circumstances, wet sowing is in spring and autumn, ditching according to row spacing, with a depth of about 10 cm, a sowing depth of about 7 cm, and a covering of about 3 cm. Of course, garlic farmers can choose how much to plant based on the local* soil and topography, but remember to do proper thinning and seed selection.

For disease prevention and treatment, use 3% phoxanthion granules per mu or 15% chlorpyrifos granules per mu evenly spread on the ground, plough into and re-sow them. It can effectively control maggots on the ground. According to the growth cycle of garlic, the seeds are replaced in different places, the planting land is constantly changed, and the quality of garlic seeds is continuously improved, which has a certain rejuvenation effect, and the greater the difference, the better the effect.

Pests and diseases, garlic has been planted for many years, and the seedlings have weak resistance and are susceptible to diseases. For example, root-knot nematodes multiply in the soil year by year, destroying the garlic root system, affecting the normal development of garlic, and causing the plant to be short. Excessive application of chemical fertilizers leads to the increasing salt content of the soil, aggravates soil salinization, and weakens the ability of garlic roots to absorb water and fertilizer, which in turn affects the growth of garlic.

It can be evenly sprinkled on the ground with 3% phoxanthion granules mu or 15% chlorpyrifos granules mu at the time of sowing, and then sow them into the soil, which can effectively control maggots.

It can be evenly sprinkled on the ground with 3% phosphine granules or 15% chlorpyrifos granules per mu at the time of sowing, ploughed into the * and then sown. It can effectively control maggots, etc.

High temperatures are not suitable for growing garlic. Because garlic likes to be cold, the suitable temperature is -5-26. Garlic seedlings have the strongest cold tolerance at the 4-5 leaf stage, and are the most suitable for wintering.

Suitable conditions for growing garlic:

Temperature: Likes cold and cool, suitable temperature is -5-26. Garlic seedlings have the strongest cold tolerance at the 4-5 leaf stage, and are the most suitable for wintering.

Light: Garlic that completes spring flowering begins to differentiate flower buds and scale buds under the conditions of long sunlight and high temperature for more than 13 hours, and is only suitable for stem and leaf growth in a short and cool environment.

Moisture: Likes moisture and is afraid of drought.

Soil and nutrients: Fertile loam soils that are rich in organic matter, loose and breathable, and have strong water retention and drainage performance are more suitable for soil requirements.

No, high temperatures above 30 degrees Celsius will affect garlic germination.

Temperature at which garlic is grown:

Garlic prefers a cold environment, through the dormant garlic cloves, at 3 5 o'clock to begin to germinate, the optimal temperature is 12 20, 30 or more to inhibit germination. The optimal temperature for garlic seedlings is 12 16 and can tolerate low temperatures of -10 for a short time. During this period, if the temperature is high, it will enhance the respiration of the plant, so that the nutrients are consumed more, and the high temperature is accompanied by drought and lack of water, which will make the leaf tissue age, more fiber, and poor quality.

Therefore, the green garlic sown in autumn should be harvested before the spring is warm, so that the product is tender and juicy. The temperature requirements for garlic are as follows:

1.Germination period.

1) Minimum temperature: 3-5.

2) Optimum temperature: 12-20.

3) Maximum temperature: 30.

2.Seedling stage.

1) Minimum temperature: -10.

2) Optimum temperature: 12-16.

3) Maximum temperature: 25.

3.Bulb formation.

1) Optimum temperature: 15-20.

2) Maximum temperature: 26.

The differentiation of flower buds and scale buds requires low temperature, and can generally be completed during the storage period or after timely planting. The optimum temperature for the flowering and bulb formation period is 15 20; Above 26, the leaves are yellow, the growth of the bulb slows down, and it enters a dormant state. Therefore, regardless of spring or autumn sowing, the bulbs are harvested before the summer solstice high temperatures.

If it is sown late, it must also be harvested before the summer solstice. Therefore, garlic should not be sown late, because the shortening of the growth period will seriously affect the clove and yield of garlic.

Normal planting is in the fall, around October. It's okay to make bonsai, but if the temperature is high, the garlic sprouts will be pumped quickly, and the shape is difficult to control.

Growing garlic has the following requirements for soil and climate:

1. Soil: Garlic likes loam soil with a soil thickness of more than 1 meter, a groundwater level of less than 1 meter, and a soil pH value between the pH value of the soil (close to neutral), rich in organic matter.

2. Climate: The average annual temperature is between 13-15, the annual precipitation is 600-900 mm, and the minimum temperature in winter is above minus 18.

Garlic is a string-shaped fleshy root with no root hairs, so the root system has weak water absorption and fertility absorption, and at the same time, the bulb grows and expands in the soil, so garlic should be planted in the plot with loose soil, rich organic matter, good air permeability, good water retention and drainage, more fertilizer in the front stubble, and less fertilizer absorption.

Garlic has a wide range of adaptability to the soil, sandy soil, loam soil or night tide land can be planted, but sandy loam soil is better, because sandy loam soil is loose and warm, suitable for root development, early greening, early sprouting, garlic is large and spicy, garlic is easy. The sandy soil leaks water and fertilizer, and the product has a strong spicy taste; Clay soil is hard and has poor air permeability, and garlic grows small and pointed; Excessive soil moisture, poor drainage, lack of air, garlic cloves are easy to rot, causing garlic maggots; The alkaline soil alkali is heavy and easy to hurt the garlic mother, resulting in a lack of seedlings. It is difficult to get a good harvest by growing garlic in these types of land.

Plots with thin soil, less organic matter, high alkalinity, and alkali return in early spring are not suitable for planting garlic. In addition to the requirements of soil quality, the land for planting garlic should also choose plots with higher terrain and low groundwater level to prevent waterlogging, rotten petals and rotten heads. In the south, where there is a lot of rain and waterlogging or the groundwater level is high, garlic should be planted on high furrows.

Garlic prefers slightly acidic soils, and a pH of 6 is preferred. Garlic is planted on alkaline soil, and garlic seeds are easy to be corroded, so that the seedlings grow poorly, resulting in more one-headed garlic and smaller garlic.

Garlic has high requirements for soil fertility, so it is advisable to use delay-acting farmhouse fertilizer as base fertilizer to improve soil physical and chemical properties. The amount of basal fertilizer per mu should be more than 5000 kg. The base fertilizer must be fully decomposed, mashed, sifted, and mixed with the soil when applied.

"Evenly distributed" is the key measure for planting garlic. If there is raw manure or manure in the base fertilizer, it is easy to "burn" the garlic mother and affect the growth of seedlings. Garlic fertilization should be mainly nitrogen fertilizer, and nitrogen, phosphorus and potassium should be complete.

It can be applied to plant ash and kang soil at the time of land preparation or at the seedling stage. It is reported that high-yield fields with kilograms of fresh garlic per mu need to absorb 21 kilograms of nitrogen, 5 kilograms of phosphorus and 15 kilograms of potassium.

The nutrients required by garlic seedlings are mainly by the mother petal**, so there is no need to apply fast-acting fertilizers at the seedling stage. Garlic needs more nutrients in the early and middle stages of vigorous leaf growth and bulb expansion, so water and fertilizer must be sufficient during this period to ensure that the plant grows vigorously, garlic sprouts grow fat, and garlic can fully develop and expand. When fertilizing, it is necessary to apply a small amount and multiple times according to the characteristics of the garlic root system that is weak and need more fertilizer, and water immediately after fertilization to facilitate root absorption.

In the late stage of bulb expansion, the leaves of the plant gradually wither yellow, the root system is senescent, the amount of fertilizer absorption is reduced, and the top dressing is generally no longer required, especially the nitrogen fertilizer should be controlled to prevent the garlic from splitting and scattering.

Garlic likes cold and cool, is more cold-tolerant, grows at a temperature of 12 to 25 degrees, and seedlings can tolerate low temperatures of -3 -5 degrees.

17 degrees Celsius to 22 degrees Celsius is appropriate.

From the end of September to the beginning of October in the solar calendar, it is best to plant garlic at night and at a temperature of 5-25.

Garlic seedlings grow at high temperatures. Garlic sprouts generally grow well at 15-25°C. Generally, spring and autumn are more suitable for the growth of garlic seedlings, because the temperature in summer is too high, and the temperature in winter is too low, which has a certain impact on the growth and development of garlic seedlings.

Growth requirements

1. Temperature: like cold and cool, suitable temperature in -5-26. Garlic seedlings have the strongest cold tolerance at the 4-5 leaf stage, and are the most suitable for wintering.

2. Light: The garlic that completes spring flowers begins to differentiate flower buds and scale buds under the conditions of more than 13 hours of long sunshine and high temperature, and is only suitable for the growth of stems and leaves in a short and cold environment.

3. Moisture: like moisture and fear of drought.

4. Soil and nutrients: the soil requirements are not strict, but the fertile loam soil rich in organic matter, loose and breathable, and strong water retention and drainage performance is more suitable for rent.
