Sulphate is recommended for shed vegetable topdressing

Fruit and vegetable vegetables are mostly planted from late October to mid-November.

When planting fertilized fruits and vegetables, we will open a 15-20 cm deep ditch between each two planting ridges, applying 30 kg of diammonium per acre and 15-20 kg of urea, while pouring water into the ditch. Buried trench. When planting the seedlings, apply a small amount of diammonium per two plants, about 40 kg per mu.

In the winter topdressing of ammonium sulfate for topdressing, if urea is used, the nutrient decomposition of urea is slow due to low soil temperature, so the fertilizer efficiency is slow; although the use of ammonium bicarbonate is quick, the ammonia volatilization in ammonium bicarbonate is easy to produce in a closed environment of greenhouse. Fat damage. Ammonium sulphate can overcome the shortcomings of the above two kinds of chemical fertilizers. Therefore, in winter, it is advisable to apply 20-30 kg of ammonium sulphate per acre. The fertilizer should be dissolved in water beforehand, and then the fertilizer should be applied with water. Usually every other time, water is poured once.

It is a bio-organic and inorganic compound fertilizer used as a base fertilizer, with comprehensive nutrients, long-lasting fertility and quick fertilizer effect. It is used as a top dressing, with quick fertilizer effect and remarkable effect. It is an ideal compound fertilizer for vegetable fields. 120 kg per mu is used as the base fertilizer. When the vegetables are planted, they are applied or ditched; 40 kg per mu is used as top dressing, shallow ditch is applied, and the soil is filled after burying.

It is necessary to add carbon dioxide to produce vegetables in the greenhouse. Tests have shown that cucumber carbon dioxide production can increase production by more than 35%. The leafy vegetables are preferably applied with carbon dioxide in the early stage of growth, and the melons and fruits should be applied from the beginning of flowering. Generally, the carbon dioxide topdressing is carried out at 9-11 am on a sunny day. Carbonammonium + sulfuric acid or baking soda plus sulfuric acid can be used to produce carbon dioxide after mixing, so that the carbon dioxide content in the shed reaches 1000 mg/kg. Do not ventilate when applying carbon dioxide. Appropriate ventilation after 1.5 to 2 hours of application. If carbon dioxide solid particle gas fertilizer is applied, 40 kg per mu is required, which can be directly applied or buried in the surface, and the effective period can be more than 45 days.
