Chive Summer Planting Fertilization Techniques and Precautions

Chives belong to the Liliaceae family and are a perennial root vegetable with strong adaptability, cold and heat tolerance, and are cultivated everywhere across China. So what clever fertilizer tricks are there for chives? What are the precautions for summer planting? Let's take a look together below.

I. What clever fertilizer tricks are there for chives?

For chives grown at home, apply fully decomposed organic fertilizer once each year in March and June. Organic fertilizer contains a large amount of nitrogen, which can make chives grow vigorously. Chives differ from other plants in that they can be harvested once they reach a certain height, and after cutting, the chives can grow again with sufficient water and nutrients. So in order to provide chives with sufficient water and nutrients, topdressing and irrigation can be carried out 3-4 days after harvesting.

Topdressing is mainly nitrogen-based, and an appropriate amount of manure and urine can also be added. It can be applied together with water, or applied first in furrows followed by watering. After harvesting, topdressing must wait until the harvesting wounds have healed before watering and fertilizing, otherwise the wounds are prone to rotting and fertilizer damage can occur. If manure and urine are applied, they must also be diluted in advance and fully decomposed, otherwise pest problems are likely to occur. Chives should be watered and fertilized once after each harvest, so that the newly grown chives are as thick and green as the first crop.

In summer, chives will produce chive flowers, so before the flowering period, additional phosphorus and potassium fertilizer can be applied to promote flowering. The common rural wood ash can also be applied to meet the phosphorus and potassium needs of chive flowers, and wood ash can also prevent the occurrence of pests and diseases in chives.

Chives are not tolerant of waterlogging. Being in waterlogged soil for a long time tends to cause root rot, so during the rainy season drainage should be timely, and during the dry season watering should be timely, so that chives are kept in a good growing environment and can grow healthily.

II. Precautions for summer planting of chives

1. Avoid harvesting

High summer temperatures lead to low nutrient accumulation and high consumption in chives, affecting plant growth, and the leaf tissue fibers increase, the texture becomes coarse, and growth weakens. From late June to early August, harvesting should be stopped to benefit root development.

From August to September, 1-2 harvests can be made, and harvesting should stop after late September. For the last harvest, the stubble should be left slightly higher. Especially for chives planted the year before last, harvesting should stop during the high-temperature summer period, and a spray bottle should be used to sprinkle water once each morning and evening to keep the soil surface moist, but pouring water over them should not be done.

2. Weeding

Summer has high temperatures and lots of rain, and weeds proliferate, affecting the growth of chives, so farmers should remove the weeds in a timely manner.

3. Topdressing

Attention should be paid to applying microbial bacterial fertilizer such as Rujin. Because in hot and dry seasons, the leaf tissue of chives becomes coarse and hard, quality deteriorates, and edible value is low, so at this time harvesting should be stopped, and chives should be topdressed in a timely manner to prepare for autumn production. For topdressing, it is advisable to flush-apply fully decomposed chicken manure, preferably a good-quality bio-organic fertilizer. For example, Rujin chicken manure fermentation organic fertilizer is a very good fermentation agent for fermenting and decomposing chicken manure. It has the characteristics of fast fermentation, good fermentation, being able to ferment at both high and low temperatures, greatly shortening production time, and reducing costs.

4. Removing bolting stalks

Because chives consume a large amount of nutrients when flowering and setting seed, apart from seed-production fields, the young tender chive bolting stalks should also be removed in a timely manner to cultivate high-yielding plants.

5. Preventing and controlling Fusarium wilt

In the high-temperature summer season, chives are prone to Fusarium wilt, especially after heavy rain followed by intense sun exposure, disease occurs near the ground, and in severe cases the whole plant dies. Therefore, in summer management, attention should be paid to drainage and waterlogging prevention, and yellow leaves should be removed to keep good ventilation between rows.

6. Preventing lodging.

Due to favorable factors such as no harvesting, sufficient fertilizer and water, and vigorous growth, chives often lodge in summer. After lodging they are prone to rotting and can induce epidemic disease, causing death. Therefore, farmers need to take timely measures to prevent lodging, such as not applying excessive nitrogen fertilizer, watering chives with an appropriate amount of water rather than too much, frequently preventing waterlogging during heavy rain, and trimming the chive leaves shorter when they grow too long and lodging may occur. All of these are good methods for preventing lodging.

In summer, this hot and humid season, we need to manage chives well, pass safely through the dangerous period, and effectively improve the quality and yield of chives.
