Planting management technology of broccoli

1. The seedlings are ready

Seedling is the basis of high yield of broccoli, so we must pay attention to it. Three days before planting, the seedbed should be disinfected and sprayed with Ruimiaoqing 8ml/ bucket water + Yiwei 20g / bucket water + Emile 5g / bucket water, so that the aseptic and insect-free seedlings should be planted, and the liquid should be sprayed through so that the liquid could flow to the rhizome.

2. Apply sufficient fertilizer to the land preparation

If broccoli wants to have a high yield, the base fertilizer is the most important, and it must be fertilized reasonably and evenly. Base fertilizer includes three kinds of fertilizer, ① organic fertilizer: high quality organic fertilizer per mu 2 square; ② fertilizer: urea 30 jin, calcium superphosphate 60 jin, potassium sulfate 10 jin (or high nitrogen and high phosphorus potassium compound fertilizer 50 jin); ③ trace elements: Ciba boron and zinc fertilizer 150g, which is the key to high yield of broccoli, the purpose is to supplement trace elements, balanced fertilization, to promote higher yield of broccoli.

Usage: before soil preparation, organic fertilizer, chemical fertilizer and Ciba boron and zinc fertilizer are mixed and spread all over the field, and then the soil is prepared.

3. Dip in the root to prevent diseases and insect pests

In order to reduce root diseases and insect pests and promote slow seedling of broccoli, root dipping treatment should be carried out before planting. Every 20ml Gaoqiao + 20g Yimi + 10ml bright shield mixed with water 4mur5jin, add appropriate amount of soil, stir into mud paste, after emergence, dip it in the mixed solution and then plant it. This method can stimulate broccoli to take root as soon as possible, the roots are strong, reduce the harm of underground pests, and the effect of increasing yield is obvious.

4. prevent dead seedlings after planting.

In various plots of continuous cropping of broccoli, the occurrence of dead seedlings after planting will be aggravated, that is, stem rot, but it will be too late to prevent and cure the dead seedlings, so if you want to prevent dead seedlings, you must spray after planting. Spraying Ruimiaoqing 8ml/ bucket water + Yiwei 20g / bucket water, or silver farinoli 20ml/ bucket water can be used for prevention and treatment.

5. Timely prevention of diseases

There are not many diseases in broccoli after planting, mainly the black rot of leaves, which can be prevented by Antaisheng 25g / bucket water + Wanhua 25g / bucket water spray every 15-20 days. In addition, to promote growth in high temperature weather, spray Rippel 10g / bucket of water + Ciba potassium dihydrogen 30g / bucket of water.

6. Insect pests and their control methods

⑴ is the white stripe on the leaves of broccoli and the insect path in the middle of the mesophyll.

Control method: avermectin 20ml/ bucket water + enemy kill 4ml/ bucket water spray control.

⑵ Lepidoptera is the most serious pest of broccoli, including Pieris rapae, Plutella xylostella and Spodoptera exigua.

Control methods: in the peak period of moth occurrence, spraying rice 15ml/ bucket water on the leaf can last for a long time, and the effect period of one spray is more than 20 days, and the permeability is strong. Foliar spraying can control the insects inside the leaves.
