Often make mistakes in mushroom planting

Strawberry cultivated in small arch shed has strong plant growth, can mature 19-22 days ahead of time, the harvest time is 13 days longer than that of open-field cultivation, and the total yield is 17% higher than that of open-field culture. the key points of cultivation techniques are as follows:

First, build a shed

The small arch shed can generally be set according to the width of two cultivated beds (about 3m wide). Insert the two ends of bamboo slices or wooden poles into the outer edge of the back of the north and south border, insert one every 0.5m along the length of the border, and properly bury the column support on the back-death of the middle border, so that the height of the middle arch of the scaffolding is 1m and the length of the shed is 10m 20m. To facilitate ventilation and management. The shed runs from north to south, and the scaffolding is covered with 0.06mm thick polyethylene film.

II. Colonization

From late July to early August, stolon seedlings or new stem seedlings with 5 or 6 leaves, short and thick stems and many new roots were selected and planted. The cultivated field should choose fertile soil and apply high quality mature circle fertilizer 700~800kg and calcium superphosphate 35~50kg every 667m ~ 2. Planting according to row spacing 25cm (6 rows per row) and plant spacing 20cm. Watering immediately after planting, once for each major watering in the first 4-5 days: after slow seedling, 2-3 leaves were opened, combined with watering, urea 7.5~10kg was applied every 667m2 to promote the formation of strong seedlings and flower buds.

III. Field management

1. In the middle of December, the soil was watered with frozen water before freezing, and when the surface was slightly dry 3-5 days later, the seedlings on the border were covered with 0.015mm thick plastic film. Pull the plastic film tight, close to the ground, and compacted with soil around. Plastic film mulch covered wheat straw and rice straw with 3cm thick to ensure that the seedlings survived the winter safely.

two。 The shack began in early February of the following year. If the greenhouse is fastened too early, the seedlings will be vulnerable to cold snap after sprouting, and too late will reduce the effect of early ripening and increasing yield of strawberries. Before buckling the shed, remove the mulch on the border, and then put the plastic film cover on the scaffolding. In mid-April and late April, when the natural temperature can meet the needs of strawberry growth and development, the shed can be opened so as not to overheat the greenhouse and affect the flowering and fruiting of strawberries.

3. The shed should be closed within 1 week after buckling, so as to promote the rapid rise of air temperature and ground temperature in the shed and make the plant germinate early. After sprouting, uncover early every night, and gradually transition to early uncover and late cover. During the period from sprouting to budding of strawberry, the greenhouse temperature should be controlled at 15: 20 ℃, the flowering and fruiting stage should be controlled at 20: 25 ℃, and the maximum should not exceed 35 ℃. When the heart buds are all gathered on the film, and the new buds are exposed, the plastic film is all close to the ground and continues to protect the root system. Strawberry entered the growth and budding stage, topdressing phosphorus and potassium compound fertilizer 10~15kg every 667m2. Less or no nitrogen fertilizer should be pursued. Generally speaking, as long as the soil is not dry, there is no need to irrigate, lest the humidity is too large, resulting in the growth of seedlings, which is not conducive to the results.

IV. Harvest

The fruit can be harvested when it is ripe in order to avoid rotten fruit due to excessive temperature and humidity in the shed.
