How to fertilize the most New Zealand flowers

Broccoli is a kind of cauliflower, also known as broccoli. Because broccoli is more nutritious than ordinary cauliflower and tastes much better, the price and sales of broccoli are higher than ordinary cauliflower in the market. In order to increase the yield of broccoli, how to apply fertilizer scientifically is very important in the process of broccoli planting. So today let's learn about the fertilization technology of broccoli.

1. Base fertilizer

Before broccoli is planted, sufficient base fertilizer is needed, and farm manure and organic fertilizer are the most commonly used. One of the principles that we should pay attention to when applying base fertilizer is to apply it again, and it must be fully applied. The amount of fertilizer used per mu is generally controlled at about two to 2500 kilograms. In addition to farm manure, it is also necessary to properly use compound fertilizer, urea and phosphorus and potassium fertilizer. Farm manure can be used in conjunction with new high-fat membrane, which can improve fertilizer efficiency. Finally, the base fertilizer should be mixed and balanced with the soil to avoid the spread and loss of fertility.

2. Seedling fertilizer

About a week after broccoli is planted, the seedlings will basically grow new roots and leaves, and seedling fertilizer is needed to restore the growth of the seedlings. Seedling fertilizer is generally urea-based, combined with a small amount of potash fertilizer. About six jin of urea and five jin of potash fertilizer are generally prepared per mu and irrigated according to a certain proportion of water, which can dilute the concentration of fertilizer and is beneficial to the absorption and utilization of nutrients by broccoli seedlings.

3. Growth fertilizer

Broccoli seedlings need to be fertilized again about 20 days after planting, in order to promote the growth of broccoli, enter the budding stage as soon as possible, and improve the growth of broccoli plants, so it is called growth fertilizer. Then the growth fertilizer is generally topdressing by ditching and shallow burying, mainly with ternary compound fertilizer, and the amount of fertilizer per mu is controlled at about 40 jin. Of course, we can also use acupoint application, but acupoint application is mainly based on water-soluble fertilizer, and the dosage can be controlled at about 10 to 20 jin.

4. Budding fertilizer

When broccoli begins to bud, it is necessary to apply budding fertilizer in time. During this period, the main fertilizer is the ternary compound fertilizer of nitrogen, phosphorus and potassium, but it needs to increase the use of potassium fertilizer appropriately, and it also needs to be combined with extra-root fertilization. The amount of three-yuan compound fertilizer per mu is generally about 40 jin, and the amount of potash fertilizer is about 10 jin. Extra-root fertilization is mainly trace element fertilizer, according to the specific situation, supplement trace element fertilizer, which can effectively improve the yield and quality of broccoli.

5. Topdressing in the later stage

The main purpose of topdressing in the later stage is to promote the growth of broccoli buds, and topdressing after each harvest of broccoli can promote the growth of new buds, which is very effective to improve the yield and quality of broccoli. In the later stage, the way of topdressing, the amount of fertilizer and the type of fertilizer are basically the same as that of budding fertilizer. the only thing to pay attention to is the need to properly spray foliar fertilizer to prevent plant aging and reduce yield.

Broccoli is generally fertilized according to these steps in the process of planting, and its fertilization method is mainly related to its growth characteristics, fertilizer demand characteristics and soil fertility. The introduction of fertilization technology above is relatively simple, but it is also easy to understand. I hope everyone will be more smooth in the later stage of planting.
