Field management of arrowhead

Pleurotus ostreatus is a perennial herb of the family Alismatidae, and it is also a very common vegetable in our life. There is a certain cultivation area in all parts of our country, but it is mainly in the south. Pleurotus ostreatus integrates edible, medicinal and ornamental values. it has strong effects such as anti-cancer and anti-cancer, detoxification and diuresis. However, it is not so easy to grow, need careful management, the following editor brought the field management method of growing mushrooms, let's have a look!

1. Seedling management

The seedling management of Pleurotus ostreatus is very important, because the seedling stage is the most vulnerable period, poor management leads to the death of seedlings and reduces the yield. After successful planting, the seedlings should be observed regularly, sometimes due to strong winds, rainstorms and other weather reasons lead to stagnant water and loosen the soil, the seedlings are not strong enough, easy to tilt or lodge. At this time, we should straighten up the sloping seedlings in time to help them 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 to ensure the full seedling and yield. Do a good job of weeding to prevent weeds from grabbing the growth and nutrition of seedlings and affecting the development of seedlings.

2. Picking leaves and wiping buds

After 2-3 weeks of planting, the growth of Sagittaria plant was observed, and when the leaves of the plant grew 6-8 leaves, an intertillage weeding was carried out. Remove the tillering seedlings in the middle of the plant, reduce the consumption of nutrition and prevent the snatching of nutrition. Then remove the three oldest leaves and bury them deep in the soil along with the petiole. Then pick the 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, the yield is more, so the demand for nutrition is relatively large, sufficient nutrition can ensure the sturdy and high yield of the plant. Therefore, we should apply fertilizer properly during the whole growth period, and give priority to nitrogen fertilizer in the early growth period, combined with the right amount of phosphorus and potassium fertilizer. Like picking leaves, they also chase fat about once every half a month. However, in the later stage, it is necessary to control the application of nitrogen fertilizer to prevent Sagittaria from growing, resulting in a decline in field permeability, affecting mushroom formation and reducing yield. After entering the mushroom-setting period, it is necessary to re-apply fertilizer to promote mushroom formation and prevent undernutrition. When fertilizing each time, we should pay attention to whether the plant is wet or not, and apply it after the dew of the plant is dry to prevent fertilizer damage.

4. Pest control

The pest control work of Cigu is very important, we should understand the high incidence period of all kinds of diseases and insect pests. Do a good job in preventive measures, strengthen field management, the common diseases and insect pests are zebra disease and aphids, we should master the prevention and control measures of all kinds of diseases and insect pests. During the growth period, the field permeability should be strengthened, old leaves and diseased branches should be removed, and ventilation should be improved. it is best to carry out rotation for more than two years, and the incidence of continuous cropping will be greatly increased. After the onset of the disease, the specific diseases and insect pests should be checked in time, and then the corresponding control measures should be used. if the disease is serious, the plants should be pulled out immediately to prevent the disease from spreading.

In order to promote the growth of Sagittaria plant and improve the mushroom rate, the top of Sagittaria should be pressed 8mm after picking leaves. It can effectively inhibit the growth of aboveground plants, improve the mushroom rate and ensure the yield. The above is the editor's brief introduction to the field management of Cigu. That's all for today's article. Thank you for your reading and support. If you want to know more related information, please continue to follow us!
