Field management of Pleurotus ostreatus (scissors grass)

Pleurotus ostreatus is not only a kind of vegetable, but also a kind of medicinal herb, which integrates edible, medicinal and ornamental value, and has high economic value. today, the editor will introduce to you the field management of Pleurotus ostreatus.

1. Seedling management

The seedling management of Pleurotus ostreatus is very important, because the seedling stage is the most fragile period, and poor management leads to the death of seedlings and the reduction of yield. the seedlings should be observed regularly after successful planting, sometimes due to strong wind and rainstorm and other weather reasons, the seedlings are not strong enough, and the seedlings are easy to tilt or lodge. At this time, we should straighten up the tilted and lodging seedlings in time to help the seedlings continue to grow. But the damage is too great, the seedlings with serious diseases and insect pests should be pulled out in time and then make up the healthy seedlings, ensure the seedling and yield, do a good job of weeding, prevent weeds from grabbing the growth and nutrition of seedlings, and affect the development of seedlings.

2. Picking leaves and wiping buds

After 2-3 weeks of planting, observe the growth of Sagittaria plant. When the leaves of the plant grow 6-8 leaves, carry out an intermediate ploughing and weeding work, remove the tillering seedlings in the middle of the plant, reduce the nutrient consumption, and prevent the snatching of nutrients. Then remove the three oldest leaves, bury them deeply in the soil with petioles, and pick leaves every half a month until the peak period of plant growth at the end of October. And in the process of growth, we should also follow the soil conditions according to the appropriate ploughing and weeding, do a good job of sprouting, properly inhibit plant growth, prevent excessive growth, and reduce yield.

3. topdressing at the right time

The growth ability of Sagittaria is relatively strong and the yield is high, so the demand for nutrition is relatively large, and sufficient nutrition can ensure that the plant is sturdy and high-yield. therefore, it is necessary to apply fertilizer properly during the whole growth period, mainly nitrogen fertilizer in the early stage of growth. with the right amount of phosphorus and potassium fertilizer, like picking leaves, it is also necessary to control the application of nitrogen fertilizer in the later stage to prevent the apprenticeship from growing. Lead to the decrease of field permeability, affect the mushroom setting, reduce the yield, re-apply fertilizer after entering the mushroom setting period, promote mushroom setting, prevent undernutrition, pay attention to whether the plant is wet or not, and apply it after the plant dew is dry to prevent fertilizer damage.

4. Pest control

The prevention and control of diseases and insect pests is very important. We should understand the high incidence period of all kinds of diseases and insect pests, take preventive measures, strengthen field management, and the common diseases and insect pests are spot disease and aphids. We should master the prevention and control measures of various diseases and insect pests. During the growth period, we should strengthen field permeability, remove old leaves and diseased branches, improve ventilation and ventilation, and preferably carry out rotation for more than two years. The incidence of continuous cropping will greatly increase, after the disease should be timely examination of specific diseases and insect pests, and then use the corresponding prevention and control measures, serious disease should be pulled out of the field immediately to prevent the spread of the disease.

The above is the field management method of Pleurotus ostreatus. I hope I can help you!
