One of the myths: How good is it to fertilize?
Cucumber high yield can not be separated from fertilization, this is no doubt. But it is not that the more fertilizer is applied, the higher the yield. The key is to apply what fat, how to use. The amount of fertilizer can not be determined by only a few kilos, but depends on the inherent content and composition of fertilizer. "Fertilizers are not in quantity but are strong enough for the road." Scientific fertilization is very knowledgeable, and it is not possible to apply fertilizers blindly based on perceptual experience. Only in accordance with the characteristics of cucumber fertilizer requirements and specific fertilizer supply conditions in individual sheds, scientific and rational use of high-quality fertilizers and balanced overall fertilization can achieve high quality and high yields of cucumbers.
Misunderstanding 2: The high output of seedlings
Many vegetable farmers always want to grow thicker when they plant seedlings. They think that trees produce more and more. Especially in the past two years, the cucumber seedlings have been thicker year after year, but the yield has not been able to be put up. As a result, the diseases are serious and they are still fighting drugs. Some people are afraid of death in the winter, but management can not keep up, dead seedlings are not a dead one, once a piece of dead seedlings, planted again thick and in vain. In fact, low winter temperatures, weak light, poor crop photosynthesis, reasonable and sparse planting can produce high yields. Plants too dense will win due to the glory, the sinking rate will decline. Poor ventilation is easy to infect a variety of real and bacterial diseases. Moreover, the leaves are difficult to fight drugs and it is difficult to completely cure once the disease spreads. There are many such examples: When the melons were very thick, they did not pick melons. Afterwards, some of the melons were removed, and the output went up.
Misunderstandings 3: Zhai Zi Wang with Guaduo
Many people think that Xunzi Wang is a good phenomenon. After planting the seedlings, they are not properly controlled. Instead, they are allowed to prosper. In fact, more than enough leaves will grow. Overgrowth of nutrition will inevitably affect reproductive growth. The long leaves and large melons will grow thin, especially the cucumbers cultivated in the two crops. Seedling stage should master the control of the roots to promote rooting; melon should grasp the plant strong but not prosperous, both long pods and melons; middle and late mulch protection against premature aging, and try to extend the melon period, so as to create a high yield.
Misunderstanding 4: fight drugs less
Some vegetable farmers in the daily management of cucumber, every 2 to 3 days will be playing a drug, that the game is straight and sick, not playing hard will certainly not work. In fact, fighting drugs, not only interfere with the normal birth of plants, but also is not conducive to their own antibiotics, disease resistance but decreased. The key is to control the rickets according to the season, choose the good drugs for medicine, so that economical and efficient, while doing a good job of ventilation and dehumidification management, once a week to fight drugs that can ensure the normal growth of cucumber. Buying a good medicine is more expensive than listening to it, spending less money on it, buying cheap goods, listening to saving money, losing control of the disease, and delaying the loss of output.
A microtome (from the Greek mikros, meaning "small", and temnein, meaning "to cut") is a tool used to cut extremely thin slices of material, known as sections. Important in science, microtomes are used in microscopy, allowing for the preparation of samples for observation under transmitted light or electron radiation.
Microtomes use steel, glass, or diamond blades depending upon the specimen being sliced and the desired thickness of the sections being cut. Steel blades are used to prepare sections of animal or plant tissues for light microscopy histology. Glass knives are used to slice sections for light microscopy and to slice very thin sections for electron microscopy. Industrial grade diamond knives are used to slice hard materials such as bone, teeth and plant matter for both light microscopy and for electron microscopy. Gem quality diamond knives are used for slicing thin sections for electron microscopy.
Microtomy is a method for the preparation of thin sections for materials such as bones, minerals and teeth, and an alternative to electropolishing and ion milling. Microtome sections can be made thin enough to section a human hair across its breadth, with section thickness between 50 nm and 100 µm.
