Qinggengcai, a kind of Shanghai cabbage, is also called Xiaotangcai. The plant is upright, with a large head and waist. The height of the plant is about 28 cm, and the spread is 28 cm × 30 cm. The leaf surface is smooth, whole, green, broad ovoid. The petiole is green and white, generous. The base is slightly concave. The following is the insect-proof cultivation technology of Qingjingcai.

Pest control cultivation

1. Stubble selection The first stubble should be non-cruciferous crops, preferably early-maturing soybean stubble, followed by root vegetables, and again spring cabbage and spring cauliflower. For continuous stubble cultivation, deep plowing is required after each stubble, and the ridges are sun-dried for 5-7 days to reduce the occurrence of pests and diseases.

2. Variety selection Choose varieties with disease resistance, strong stress resistance, good adaptability, high quality, and good commercial properties. The main varieties are Xinza No. 1, Zaoshu No. 5, and Zhongji Baijing, which can be popularized as new varieties of Shulu. Dress the seeds with 75% chlorothalonil, 50% copper succinate, 50% fortunet and 50% prodyne, and the dosage is 0.4% of the seed.

3. After the crops are harvested before applying enough basic fertilizer, apply enough basic fertilizer with deep tillage. 80-100 kilograms of organic fertilizer per acre and 1500-2000 kilograms of decomposed farmyard manure are used for base fertilizer. Use as little chemical fertilizer as possible. Each large shed is 6 meters wide, with 2 borders in the shed, with a height of 10-15 cm, leaving a walkway in the middle to facilitate harvesting.

4. Sowing and covering the net every stubble, sowing 1.25 to 1.5 kg of seeds per mu evenly, cover the floating surface with sunshade nets after sowing, and pour thoroughly water immediately. Insect net use specifications: 20-22 mesh light silver gray insect net. Time to surf the Internet: When the pakchoi has all the seedlings, open the shading net on the border and go online immediately. Internet access requirements: Cover the entire shed with a 10-meter-wide insect-proof net, flatten the net with bricks or soil around the shed, and leave a door (screen door) at one end of the shed for easy access management.

V. Field management and top dressing: As the growth period of Chinese cabbage is short (20-25) days, on the basis of applying sufficient base fertilizer, no top dressing is required during the whole growth period. Watering: Watering depends on the climate and soil humidity. It should not be too dry or too wet. Watering is generally 3 to 4 times during the growth period. Harmless treatment of plant diseases and insect pests: As the entire process is covered with insect-proof nets, there is no need to use pesticides to prevent and control pests. The yield is generally 1,000 to 2,000 kg per mu.

Single Packed Yellow Waxy Corn Cob

For the most common waxy and sweet corn on the market, waxy corn has a higher nutrient content than regular corn, containing 70-75% starch (and almost all straight-chain starch), more than 10% protein, 4-5% fat and 2% multivitamins, with more grains, VA, VB1 and VB2 in protein than rice, with the highest fat and VB2 content. Yellow maize also contains carotenoids, such as rice and wheat. The molecular weight of waxy maize starch is more than 10 times smaller than that of ordinary maize, and the starch makes glutinous rice sticky and soft, softer than ordinary hard maize. It is more than 20% more digestible to eat than regular maize and it is suitable for people with less than perfect teeth. At the same time, it is not suitable for diabetics because of the very high content of straight-chain starch (a polysaccharide).

Waxy maize is also known as sticky maize. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dent maize. Its chemical and physical characteristics are controlled by a recessive gene, which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
