Is sticky corn high in sugar? What is the planting method?

There are many kinds of corn, including waxy corn, sweet corn, black corn and so on, among which there is a variety called sticky corn with higher nutrients than ordinary corn, and many people are not very familiar with it. Sticky corn is a very good weight loss food, high in calcium, phosphorus and vitamins. Let's take a look at whether sticky corn has high sugar content. What is the planting method?

Is the sugar content of sticky corn high?

Sticky corn is a variety of corn, just like glutinous rice is a kind of rice. Sticky corn is waxy corn, which originated in China and is the result of gene isolation and free combination, so sticky corn is not genetically modified corn. So if you want to know whether the sugar content of sticky corn is high, you just need to know the sugar content of waxy corn. The sugar content of waxy corn is very low, sweet corn tastes sweet, but its sugar content is very healthy, different from sucrose.

Second, what is the planting method of sticky corn?

1. Parcel selection

The plot should be located in the agricultural production area with no pollution source and good ecological environment in 3km. The irrigation water quality, air quality and soil environmental quality around the plot should be within the scope of the national production standards for pollution-free agricultural products. In addition, sticky corn and common maize varieties with different genetic background should be planted in isolation to avoid mixing flour to reduce fruit quality and yield, and the general distance should be more than 300m to 500m.

2. Raising seedlings

Because the seeds of sticky corn are withered and the ability of magic seedling top soil is weak, direct seeding in the field is easy to lead to lack of seedlings and broken ridges. From the aspects of striving for season, saving seed and listing in advance, it is appropriate to adopt seedling cultivation and transplanting. At present, the main varieties of sticky corn are Kennian series No. 1, No. 2 and No. 3. Greenhouse or greenhouse seedlings, with 30% to 40% rotten farm manure, 60% to 70% fertile fine soil, the right amount of calcium superphosphate, turn the soil and mix well, put into the specification of 6cm nutrition bowl. On April 20, sowing seeds in sunny days without strong cold air, 2 grains per bowl, watering through bottom water, and covering 1cm thick with moist nutritive soil. Normal management, cold injury is strictly prohibited.

3. Transplanting

After the local final frost period, corn seedlings grow to 3 or 4 leaves, which are usually transplanted around May 10. Only one plant was left in each nutrition bowl to take soil and transplant. The planting time is a little deeper, 3000,5000 plants per mu, plant spacing 25~28cm, row spacing 60~70cm.

4. Scientific fertilization

As the harvest time of sticky corn is about 15 days earlier than that of ordinary corn, the base fertilizer should be sufficient and topdressing should be diligent. Before transplanting, combined with soil preparation and ridging, the rotten organic fertilizer 2000kg and three-element compound fertilizer (15% N, P, K) 15~20kg were applied per mu. The first topdressing was before jointing of 6-7 leaves, and urea 5~6kg was applied per mu. In the second topdressing, urea 5~6kg was applied before 13-15 leaves were male. The application method is basically the same as that of ordinary corn. Under the condition of good water and fertilizer, tillering is easy to occur in the seedling stage, and excessive length of multi-ear and wrapped leaves is easy to appear in the middle and later stage. the axillary buds of tillers and ineffective ears should be removed as soon as possible, and if the wrapped leaves are too long, the top wrapped leaves should be cut off in time, and artificial pollination should be assisted in the silking stage, otherwise it is easy to reduce yield.

5. Pest control

When transplanting, 1000 times liquid of 48% Lesbon emulsion was used to control underground pests such as ground tigers and grubs. The heart leaf peak period is the key period for the control of corn borer. BT emulsion, Kuaishaling and other pesticides with high efficiency, low toxicity and low residue can be used to control the corn borer. If corn size spot occurs, the affected fields are generally sprayed with 50% carbendazim 500-600 times or 70% methyl thiophanate 800-1000 times before and after heading.

6. Chemical weeding

(1) after sowing, 90% 40~50mL emulsion or 50% Acetochlor emulsion 80~100mL was sprayed evenly on the surface before emergence.

(2) Stem and leaf treatment when monocotyledonous weeds were in 1-2-leaf stage, dicotyledonous weeds in 2-4-leaf stage, 40% atrazine emulsion 200~250mL or Yunongle water agent 80~100mL were sprayed evenly on weed stems and leaves with water 50kg.

7. Timely harvest

Green food should be harvested timely to ensure that sticky corn has rich nutrition, thin skin, no residue, good taste and high price, which can be harvested 18-20 days after silking.
