Fresh sweet corn fertilizer application technology
Fresh sweet glutinous corn has high nutritional quality and economic value. Its uses and edible methods are similar to those of vegetables and are often referred to as "vegetable corn." In the production, a reasonable fertilizer operation is to promote the early growth of strong sweet corn seedlings, regulate the growth of the population of plants in order to prevent premature aging, establish high-yield high-yield groups, adjust the nutritional status, improve the quality and flavor of fresh sweet corn, realize High yield and high efficiency are important ways.
According to the characteristics of the short growing period and the characteristics of processing and utilization of fresh sweet waxy corn, the general principles of fertilizer management are: adhere to the application of organic fertilizer and inorganic fertilizer, increase organic fertilizer, apply chemical fertilizer in an appropriate amount, and reuse basic fertilizer when fertilizing, to assist Topdressing, and increase the application of phosphorus and potassium fertilizers, the use of long-acting nitrogen fertilizer and phosphorus and potassium fertilizers with good effect.
1, increase organic fertilizer organic fertilizer can enhance soil fertility, improve soil fertility, more organic fertilizer, plant growth is stable, good grain quality.
2. Reasonable fertilizer fertilization Nitrogen fertilizer can significantly increase the yield of sweet corn, but excessive nitrogen fertilizer reduces the lysine and sugar content in grains, and the phosphorus and potassium fertilizers are conducive to the increase of lysine and sugar. The increase of P and K fertilizers reduced the starch content, increased the nutritional value of the ear, improved the processing quality and palatability of the grain, and increased the value of the commodity. Especially in the range of general soil fertility, the increase of potassium fertilizer can improve the nutritional quality of sweet corn and sugar content of stalk, and increase the protein, lysine, fat and total sugar of grain significantly. However, excessive application of potassium can inhibit the formation of lysine in corn kernels. Fertilization strategy should be based on different fertility levels and different varieties of fertilizer requirements for formula fertilization, in the conditions of high nitrogen fertilizer, combined with the application of P, K fertilizer, can obtain high yield at the same time, to obtain better economic benefits. The total use of nitrogen (N), phosphorus (P2O5), and potassium (K2O) is about 16-20, 10-15, and 15-20 kg, and the amount and time of application depends on the level of soil fertility and plant growth, so as to maintain It is advisable to grow vigorously and have normal or dark leaves. The nitrogen fertilizer in the base seed fertilizer is concentrated in the sowing line between the hole, generally accounting for 30% of the total application amount, seedling fertilizer in the seedlings 3-4 leaf age when the topdressing, pay attention to the big seedlings are not applied or less, small seedlings are applied, mentioning small seedlings to promote Balance, the general amount of accounted for 10-20%; panicle should be re-applied when the 7-8 leaves spread, this time the beginning of the jointing of sweet corn, the amount of application of 40-50%, in order to promote the growth of efficient leaf area near the ear and spike Differentiation main attack big spike; sweet corn harvesting during the milk ripening period, so the grain fertilizer generally do not need to be applied, but the initial stage of grain filling should be depending on the characteristics of the previous fertilizer dosage and seedling characteristics, as appropriate, the application of granular fertilizer, you can also spray foliar biochemical agents to Promote the fullness of large panicles, promote grouting, improve the appearance of the market and the appearance of goods. Top dressing should be within 10-15 cm of the plant, combined with cultivating and weeding to deepen the cave. Phosphorus and potassium fertilizers should be applied as a base fertilizer at one time. Because the phosphorus and potassium fertilizers are less mobile in the soil, they are not easy to lose. Concentrated application to sowing lines is beneficial to root absorption. Early application of phosphorus and potassium fertilizers will promote the early growth of strong seedlings.
3. Supplementary application of corn micro-fertilizer The development of sweet corn also requires a certain amount of trace elements such as zinc, iron, manganese, boron, copper, molybdenum, and ultra-trace elements. These elements are often part of enzymes, coenzymes, or some vitamins. Although the amount is small, it is indispensable. Once it is lacking, the symptoms of deficiency are obvious, affecting the yield and quality. Therefore, in the production of sweet corn, it is necessary to pay attention to supplementing the base fertilizer or applying micronutrients to the leaves according to the soil abundance. Ensure the normal growth and development of sweet corn in order to improve the quality and yield of sweet corn. (Source: Nongbo.com)
Goji, Goji Berry, or wolfberry is the fruit of either the Lycium barbarum or Lycium chinense, Lycium is a genus name and pronounced similarly to the word "Lycos", which means wolf in Greek. Goji is pronounced similarly to its Chinese pinyin "gÇ’uqÇ". With the increase of its exports, the name "goji" is becoming more and more popular.
Goji berry ( [Goji" means [happy") has been used for thousands of years by herbalists in China to protect the liver, help eyesight, boost immune function, improve circulation, and promote longevity and overall well being. It has only recently gained popularity in the west, it has become so polar, in fact, the Time Magazine recently named the Goji berry as [super-fruit" of the year. A big reason why Goji berries have quickly become a favorite nutritional supplement is that its impressive list of ingredients. The Goji berry, also called the wolfberry, is a bright purplish red or purple red berry that comes from a shrub that is native to China. In Asia, goji berries have been eaten for generation in the hope of living longer.
