November pollution-free vegetable production calendar (3)
The optimum temperature for storage of lettuce is 0-2°C. From the beginning of winter to the end of November, the weather is not very cold. It needs heat protection and sun protection. The wind barrier in Yangshuo needs to be clamped as late as possible. During this period, during the day when the light is strong and the temperature is too high, we must cover the grass weeds and lift the grass from the shade to release the air to reduce the temperature in the bowl to prevent the evaporation of water; during the night, if the temperature is not too low, we must not cover the grass weeds. When the cold wave cools down, then cover the grass. Fourth, frozen spinach Preparation for frozen frozen spinach is strictly the key to storage. In late mid-November, the soil freezes overnight, and the spinach that is harvested can freeze quickly, leaving the spinach in a dormant state with minimal loss and a suitable harvest period. Choose a dark, well ventilated place where the sun is not shining, and arrange behind the wind barrier. Before the harvest, level the ground behind the wind barrier and make it 1.3 meters wide. Every morning, spinach leaves are frozen and cannot be harvested. The sun rises at about 10 o'clock, and the leaves start to thaw after they are frozen. When harvesting, bring about 1.6 centimeters of the main roots. Place them on the ground after the rebirth. When the weather cools down, tie them together and bundle them into large bundles with a diameter of 30-40 cm. Place the bundles on the wind barriers. Stored in advance. During the pre-storage, the root of the dish is topped and the leaves are affixed to keep the leaves from losing water. Between the bale and bale, coded in two lines. Pre-storage period is generally 4-5 days. When the temperature drops significantly, the vegetable husk is officially buried. That is to say, turn the vegetable bundle upside down so that the vegetable root is facing downwards and the leaf is facing upwards. Keep it in the same place and keep a gap of more than 10cm between the bundle and the bundle. Immediately after the excavation was carried out, the soil was buried and the vegetables were tied up. Fill the gaps between the vegetable bundles first. Then enclose the entire meat dish and make a 25 cm thick soil cover. Finally, cover the top of the package. A layer of soil, about 5 cm thick. 5. Frozen parsley is harvested from late October to early November. It is rooted and shaved, and the soil is shaken. The bundles are placed in the ground. Like the spinach, the wind barrier is in the shade at the north and can be stored until the early spring of the following year. In mid-March. If it is only stored in the Spring Festival, it can be 1-2 days before harvesting in the field. A shallow earthen pond should be dug in the back shade, 1.3 meters wide. Dig more than 10 centimeters deep from the hoe surface and put the excavated earth in full. Around the pond, shoot a 30 cm thick, 15 cm high earth gang. Excess soil is placed outside the pond and left as cover soil. That is, the earthen pond is 25 cm deep and the bottom of the pool is leveled. If stored locally, every row of oysters at the time of harvest shall firstly empty a row of empty rakes and dig in the empty rake. Because there is no wind shading, the soil temperature is not stable, and it is easily heated, so the earth ponds can be dug narrower and wider. 0.8-8 meters.
