What fertilizer can make chives grow thicker and bigger?

Leek is a common vegetable . Its growth cycle is divided into the vegetative growth period and the reproductive growth period, and each stage has its own unique nutrient requirements. So what kind of fertilizer should be applied to make chives grow thicker and longer?

What fertilizer can make chives grow thicker and bigger?

1. Application of base fertilizer

Before sowing or transplanting leeks, apply base fertilizer during deep plowing and land preparation to lay a solid nutritional foundation for the initial growth of leeks. The base fertilizer should include organic fertilizer , phosphorus and potassium fertilizer and an appropriate amount of nitrogen fertilizer. The amount applied needs to be scientifically proportioned based on the soil fertility conditions and the nutrient requirements of leeks. Too much or too little is not conducive to the healthy growth of leeks.

2. Apply fertilizer in stages

During the growth cycle of leek, a phased topdressing strategy should be implemented. In the early stage, the focus is on applying phosphorus and potassium fertilizers to promote the rapid development and expansion of the leek root system ; in the middle and late stages of growth, the supply of nitrogen fertilizer is increased to accelerate the lush growth of leaves. The amount of topdressing each time needs to be flexibly adjusted according to the actual growth conditions and nutrient requirements of the leek to ensure a balanced distribution of nutrients and avoid excessive or insufficient local growth.

3. Fertilizer and water coordination

When applying fertilizer, the proper management of water should not be neglected. Maintaining appropriate soil moisture is the key to the growth of leeks. Irrigation should follow the principle of "water when dry, do not water when not dry, and water thoroughly when watering". This is to prevent growth stunting caused by drought and to avoid root diseases caused by excessive water.

Fertilizers that are not suitable for chives

1. Nitrate nitrogen fertilizer

Excessive use of fertilizers containing high concentrations of nitrate nitrogen will cause leeks to absorb too much nitrogen, causing excessive growth and affecting the yield and quality of leeks. This type of fertilizer contains high salt content and improper use may cause soil salinization and damage soil health.

2. Uncomposted farmyard manure

Incompletely decomposed organic matter will occupy nutrients such as nitrogen, phosphorus, and potassium in the soil, hindering the normal growth of leeks. Uncomposted fertilizer may contain pathogens and insect eggs, increasing the risk of leek diseases and pests.

3. Ammonium bicarbonate

When it decomposes in the soil, it releases a large amount of hydrogen ions, causing soil acidification and affecting the growth of leeks. It contains high chloride ions, and excessive use may cause soil salinization and damage soil structure.

In short, scientific topdressing is an important guarantee for high yield and high quality of leek. During the topdressing process, it is necessary to combine the actual growth conditions and nutrient needs of the leek, accurately grasp the timing, type and amount of fertilization, and at the same time pay attention to the coordination and unification of fertilizer and water management to promote the healthy growth of leek and ultimately achieve a double increase in yield and quality.
