Cauliflower is more resistant to low temperatures, suitable storage temperature is 0 ~ 1 °C, relative humidity of about 95% is appropriate, such as low humidity or ventilation is too large, the ball loses water, wilt, loose, poor quality. Physiological disorders are caused in hypoxic (less than 2%), high-carbon (5% or more) environments, and the curd has similar symptoms after cooking, and produces odors and loses food value. Mechanical injuries can also accelerate aging and deterioration. Variety selection, cultivation requirements and harvesting Cauliflower used for storage should be selected for tight, good quality, heat-resistant or cold-resistant, adaptable mid-late maturing varieties. In the spring, we can choose to use Funon 10, Swiss snowballs, and the Dutch snowballs in autumn. In the course of strengthening management of water and fertilizers in cultivation, special attention should be paid to the rational application of phosphorus and potassium fertilizers, which can not only promote the good development of flower bulbs, but also prevent the occurrence of black heart phenomenon due to lack of potassium fertilizer. Cauliflower is also sensitive to boron and other elements. Boron deficiency can lead to cracking of the flower bulbs and, when severe, it turns brown and produces bitter taste. Boron-deficient soil should pay attention to the application of boron fertilizer. Pre-harvest measures: When the bulbs are just exposed, they will pick up the blades around the ball, gently bind them with straw ropes, etc., or break the 1 or 2 leaves near the bulbs to cover the bulbs to keep the balls. White and tender. 4 to 5 days before picking stop irrigation. Harvesting standards: bare flower bulbs, high water content, texture can be harvested when crisp. Take care when harvesting, gently pick light, choose full growth, the surface is round, the flower buds are not scattered buds at the edge, generally collected in the afternoon 4:00 to 5:00, leaving 2 to 3 white ball Cut off at the blade, if used for prosthetic storage, with the root with leaves harvested. Rainy days are not suitable for picking. Pre-reserve measures 1. Select the refurbishment to choose the diameter of about 15cm, compact ball, white, no pests, no mechanical injury of the ball, leaving 3 to 5 leaves, and cut off the lower part of the old stem. 2. Preservative treatment Before storage, 0.15% thiophanate solution may be used to dip the flower ball pedicle (not to be immersed into the flower bulb) or to use ketimulin preservative (the main effective ingredient is sec-butylamine) to volatilize and fumigate. The method is per kg of cauliflower. With 0.lmg Ke-Dao Ling preserving agent dipped in good absorbent paper or cotton cloth, evenly hung around the dish or between the cocoons and cockroaches, smoke 24 hours that can inhibit the body surface of the pathogen. The cellar, the body and the packaging objects, frame materials, etc. shall be sprayed with 0.5% bleaching liquid or fumigation and sterilization shall be carried out under the sealed condition with ketimulin preservative. 3. Pre-cooling can take pre-cooling under natural air temperature, place the product to be stored in a cool, ventilated place in time, shade during the day and open at night. If there is a cold storage, the temperature of the storage tank can be gradually reduced to 4 to 5°C, and ventilation facilities can be used to rapidly reduce the temperature of the vegetable. This method is fast and stable, and its effect is particularly good. Storage method 1. Implantation storage In areas where winter is not very cold, impregnation and easy storage can be used for storage. Before and after the beginning of the winter, the small flower bulbs that have not yet grown up were dug up and rooted, and they were planted in impotence or storage trenches with a spacing of 25 cm. The roots were filled with soil, and the leaves of the plants were bundled together to protect the flower bulbs. Immediately after planting, water should be applied to cover the cold, and when the temperature is high at noon, the air should be properly ventilated. Enter the winter season, stamp cold-proof materials, and water as needed. The temperature of the microclimate in the prosthesis area can be higher in the early stage to promote the growth and maturity of the flower bulb. To Spring Festival, flower bulbs can generally grow to 0.5kg. This method is economic and simple, and it is commonly used by the public as a storage method. 2. Storage in the cellar The pre-treated broccoli is basketed until it reaches 80% full, and it is stored in the pit. The height of the raft is determined by the height of the pit. Generally, 4 to 5 baskets are high and must be staggered. Keep a certain distance between the daytime, and arranged in an orderly manner, in order to facilitate the management and ventilation. To prevent loss of water, the plastic film was covered but not sealed. Each day, one side of ventilation is opened and the temperature and humidity are adjusted. During storage, it must be inspected frequently and it was found that the condensed water on the cover film was wiped off in time, and yellow and rotten leaves were removed immediately. The application of the method should not be too long storage period, 20 to 30 days as well. Can be used for temporary storage short-term storage of turnover. 3. Cold Storage Storage (1) Self-regulating atmosphere storage in the cold store to build a 4～4.5cm long, 1.5m wide and 2m high dish rack, divided into 4 to 5 layers up and down, and a polyethylene plastic film is laid on the bottom of the rack. The bottom of the book. Put the flower ball number to be stored on the vegetable rack, and finally use a 0.023mm thick polyethylene film to make a large bill cover outside the dish rack and seal it with the bottom of the bill. Cauliflower's own respiration can spontaneously adjust the ratio of oxygen and carbon dioxide in the account, but be aware that oxygen must not be lower than 2%, and carbon dioxide cannot be higher than 5%. Control method: By opening a special "cuff" ventilation on the large account (abbreviated account). During the first few days of storage, the respiratory intensity is relatively large. Ventilation should be done every day or every other day. With the decrease of respiratory intensity and stabilization, it can be ventilated once every 2 to 3 days. Check 1 time during 15 to 20 days of storage. Individuals with lesions should be dealt with promptly. To prevent carbon dioxide damage, sprinkle some hydrated lime at the bottom of the bill. Put some potassium permanganate carriers (bricks or foams soaked with potassium permanganate) in the vegetable rack and around the upper layer to absorb ethylene. The ratio of storage to carrier is 20:1. After a large bill cover can also be sealed, with the outside world to maintain regular trace ventilation, strengthen observation, 8 to 10 days to check once. The above method can be stored for 50 to 60 days, and the product rate is over 80%. (2) Single-flower bagging The bag is made of 0.015 mm thick polyethylene film and is made into bags of length and width of 40 and 30 cm (or depending on the size of the flower ball). Put the prepared flower ball into a bag individually, fold the bag mouth, and then put the basket stacker or directly store it on the shelf. When the code is put, the flower ball is down so that the condensed water will not fall on the flower ball. This method can better keep the bulbs fresh and white, and the storage period is about 3 months. The product rate is about 90%. The storage effect of this method is obviously better than other storage methods, and it can be widely applied in cold storage areas. Applicable to this method is to pay attention to cauliflower leaves began to fall off after two months or rot, if you need to store more than 2 months, after the removal of leaves after storage is good.
Cast iron pig slats are made of high-quality cast iron and are characterized by their durability. Not only can be used for laying the floor of pig farms, but also for sheep, cattle and other farm floor laying, but also has the effect of insulation. Its chemical composition ensures maximum strength and endurance, with vertical ribs in the same direction, so sows can get up easily. Perfect alignment of the holes between the ribs to avoid damaging the sow's nipple. Easy to clean, quick to install.
The cast iron slats we produce are very good for sows and piglets. We can produce a variety of cast iron sats, can also be based on customer requirements or customer drawings provided for production.
