One is to use enough organic fertilizer to apply base fertilizers to obtain the foundation for the harvest of Chinese cabbage. In general, the soil fertility of old vegetable fields is relatively high, and organic fertilizers should be used in appropriate amounts. However, the soil fertility of new vegetable fields is not high. It is particularly important to reuse organic fertilizers and phosphate fertilizers as base fertilizers.
The second is Qiao Shi Miao Fei. After the Chinese cabbage cotyledon grows, the main root has reached about 10 centimeters; and a lateral root has occurred, which has the ability of absorbing water and sucking fertilizer. Under the condition of insufficient base fertilizer or no application of fertilizer, a small amount of seedling fertilizer is applied per mu. 5? 7 kg urea, to promote growth. Fertilizer should focus on partial application of small seedlings, weak seedlings, and promote the formation of strong seedlings.
The third is a reasonable top dressing. It is generally the key to guarantee the high yield of Chinese Cabbage when it is necessary to seize the seedlings of the seedlings and begin to enter the rosette stage and start dressing twice. At this time, Chinese cabbage is in a period of rapid growth, and it is necessary to increase the amount of topdressing fertilizer, mainly nitrogen fertilizer, and apply N fertilizer and P and K fertilizers, or regularly apply water manure. During the growing period, the foliar sprayed with KE 891 phyto-promoter (titanium citrate) or 0.5% to 1% of urea and monobasic potassium dihydrogen phosphate diluted 1000 times can increase the net rate of Chinese cabbage and improve Product value.
Fourth, pay attention to the application of potash. Potassium fertilizer can increase the disease resistance and storage resistance of Chinese cabbage, but potassium fertilizer is often neglected in production. The amount of potassium applied is generally 20 kg of potassium sulfate or 15 kg of potassium chloride. In the absence of chemical potash, part of plant ash can be applied.
Single Packed Mottled Waxy Corn
Waxy corn comes in a variety of colours. Some people wonder if waxy corn is a genetically modified product. In fact, it is not. Waxy corn originated in China. It is caused by a genetic mutation. Artificial selection gradually led to the emergence of a type of tannin.
Waxy corn, also known as waxy corn, is sticky corn. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dented corn. Its chemical and physical characteristics are controlled by a recessive gene (wx), which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
Coloured glutinous corn is generally white, yellow, red, purple and black, with white, yellow and purple corn being the basic colours. Purple and white hybrids naturally become purple if the purple gene "beats" the white gene and vice versa, so if the two tie we see white and purple corn. Purple can turn into red and black corn, or as we often say, "red is purple and black is purple". Of these colourful corn, the most common yellow waxy corn is the most nutritious as it is rich in carotenoids...
Currently, the only genetically modified foods sold on the Chinese market are soybean oil and papaya. Waxy maize is a hybrid variety and is not associated with genetic modification. Therefore, it can be concluded that glutinous maize is a hybrid variety and has nothing to do with genetic modification.
Genetic modification is a type of "genetic engineering" in modern science and technology, which makes use of modern molecular biology techniques. Hybridisation is the mating of individuals of different genotypes to produce offspring that are different from the original "pure" breed. In a sense, it belongs to the natural exchange of genes that can occur in nature.
