The small tube is a kind of squid, which is characterized by a small body and a long and slender body, also called the squid. Squid Tube,Frozen Squid Tubes,Squid Tubes Frozen,Squid Tubes For Sale Zhejiang Industrial Group Co., Ltd. , https://www.xingyeseafood.com
Squid meat is more delicious than cuttlefish. The head and torso are longer and narrower than that of a cuttlefish, especially the end of the torso are very similar to the spearhead of a javelin, so it is called a squid. Octopus, also known as octopus, belongs to the order of the eight arms.
Both octopuses and cuttlefish have ink sacs that can release the ink. The biggest difference is that the octopus has only 8 wrists, and the suction cup on the wrist does not have a handle or toothed ring.
High-yielding Cultivation Techniques of Winter Maize
Winter corn is typically sown between late October and November, and harvested from April to May of the following year. This crop has a unique growth pattern, characterized by weak root development and limited ability to absorb water and nutrients, making its overall growth less vigorous compared to summer-sown corn. As a result, winter corn tends to be shorter in height and has a shorter growth period for the same variety. The suitable areas for growing winter corn are generally above 1,300 meters in elevation or in low-heat valleys like the Jinsha River region. Based on successful high-yield practices across different regions, key techniques such as selecting quality seeds, proper sowing time, plastic film covering, planting density, water and fertilizer management, and pest control have been developed.
First, sowing specifications and density should be adjusted according to the variety, local climate, and fertilization levels. For example, early to mid-maturing hybrid varieties with strong disease resistance, such as Yunyou 196, Yunrui 8, and Yunrui 9, are ideal choices. It's also important to select varieties that do not interfere with spring planting. Sowing dates must be carefully chosen to avoid frost damage, which can significantly reduce yield and quality. In southern areas like Linyi and Simao, where minimum temperatures occur around mid-January, sowing is usually done from late October to November to ensure a frost-free growing season.
Sowing methods often involve wide and narrow row patterns. For monoculture, a 50 cm narrow row with 90–93 cm wide rows is common, with two rows of corn planted every 40 cm and spacing of 13–17 cm, resulting in about 5,000–5,500 plants per mu. In intercropping systems, the narrow row is 42 cm, and the wide row is 133 cm, allowing for 2 rows of corn and 3 rows of soybeans or 2 rows of potatoes in between. Plant density here is slightly lower, around 4,000–4,500 plants per mu.
Soil preparation is crucial for winter corn. Fields should be well-drained, with furrows dug to improve water flow. After plowing, the soil should be broken up and leveled before planting. Seeds are sown in small holes, with two corn seeds per hole and one seedling per hole. Soybean spacing is set at 33–40 cm, with 13–17 cm between holes, and 2–3 seeds per hole. All seeds are buried deep enough to ensure good germination.
Fertilization is another critical aspect. A balanced approach of base fertilizer and top-dressing is recommended. Base fertilizer should mainly consist of organic matter, while top-dressing involves nitrogen, phosphorus, and potassium. On average, each mu requires at least 40 kg of nitrogen, 50 kg of phosphate, 20–25 kg of potash, 1 kg of zinc, and 1,000 kg of farmyard manure. Top-dressing is applied three times: first when the plant has 4–5 leaves, second when it has 6–7 leaves, and third during the tasseling stage. Using a top-dressing gun for deep application helps improve nutrient absorption.
Plastic film covering is essential due to cold winter temperatures and reduced rainfall. The film helps retain heat and moisture, significantly increasing yield. Proper film application includes fine soil preparation, leveling the surface, and securing the edges tightly. Two sowing methods are commonly used: one where seeds are sown first and then covered, and another where the film is placed after sowing. Both methods have their advantages, but the first ensures better emergence rates.
Field management plays a major role in the success of winter corn. After sowing, irrigation is necessary if the soil is too dry. Regular weeding, timely removal of the film, and controlling pests like voles are also important. Frost protection measures, such as burning straw or using antifreeze sprays, should be taken in vulnerable areas. Overall, careful planning and consistent care throughout the growing season are essential for achieving high yields of winter corn.
