Celery is one of the common vegetable varieties in our life. It is rich in various vitamins, has a fragrant smell and high nutritional value, and also has certain medicinal value, such as lowering blood pressure, supplementing iron, treating constipation, etc. efficacy. From July to August, when the celery seedlings are planted, it is now the season of harvest management after celery planting. The following series of Hui Nongwang focuses on the management and harvesting of celery after planting.
Planting management after celery planting:
First of all, we must keep the soil moist after planting, but we can not use large water to irrigate, a small amount of water can be sprayed. Now the temperature can be lowered, and the greenhouse film can be covered. By the end of October, it is necessary to topdress again. Pay attention to the cold weather, reduce watering, and not have water.
Celery pest control:
1. Diseases and control of celery cultivation
The initial symptoms of the disease such as spot blight and spot disease of celery are small spots with light brown oil immersion on the leaves, and then gradually enlarge into middle white and yellow edges, which seriously affect the commercial value of celery. Spot disease is similar to it, but it is a green spot that slowly turns brown and develops into an irregular round spot.
Biological drug control: You can use leaf-specific fertilizer, choose the phycocyanin and high anti-immune activating enzyme. These are the elements that can greatly enhance the resistance of celery. It is time to use it. The advantage is no. The pesticide residue can make the celery grow stronger. The disadvantage is that it inhibits bacteria, not sterilization.
Chemical control: use 75% chlorothalonil WP or 70% thiophanate. 22% chlorothalonil aerosol can also be used, the advantage has a strong lethal effect on bacteria, the disadvantage is that there are pesticide residues.
2. Pests and control of celery cultivation
In terms of pests, it is mainly whitefly and Liriomyza sativae, mainly living on the leaves of celery to suck the branches and leaves, causing the celery to fail to undergo normal photosynthesis and wither. The damage is relatively large.
The control method is: 23% of the enemy, 0.9% of the Afford 2000 times, 2% of the Suawei 1000-1500 times can also be used. The above biopharmaceutical may also be added to prevent the production of phytotoxicity.
Celery planting harvest:
Celery is different from other dishes. It is harvested in the form of lychee. It is to smash the outer leaves of celery that grow to a certain height. A celery sticks two to four leaves, and at the end it is uprooted. But remember to not water after each litchi, because there is a high probability that the celery will rot.
The above is the management and harvesting points of the celery planted after the small series compiled by Huinong. The above-mentioned medicaments are for reference only, and I hope to help everyone in the cultivation of celery.
