Does the night temperature turn high? There are great tricks here
As the weather gets warmer, temperatures and ground temperatures begin to rise, especially because of the problem of leggy caused by excessively high night temperatures, which has become a problem for farmers. How to control it?
Sun Jiancheng: Crafting Trees + Full Root Control and Strong Growth
The concept of Master Sun, a master planter in Dongxia Township, Qingzhou City, Shandong Province, is that the physical methods combined with good root-raising products are the key to controlling prosperity.
First of all, it is to make trees.
The purpose of the tree-building is to strengthen and enhance stress resistance. The cucumbers I planted this year are short in jointing, thick in stems, thick in leaves, and green in leaf color. These are all in line with the criteria for strong trees, and this is the temperature control. During the day, try to increase the temperature inside the shed, 30 °C or more, the purpose is to increase the temperature, reduce the temperature in the shed at night, control at 10-12 °C can be. During this period, it is necessary to pay attention to the weather forecast. If it is cloudy, the temperature in the shed during the day is less than 30°C, and the night temperature is 12-13°C; if it is sunny, the temperature in the shed during the day is high, and the rear wall heats up enough, then the night is completely You can leave the grasshopper or grasshopper in half. The general principle is that the temperature changes day and night, and try to maintain a high ground temperature, which is conducive to controlling the growth of stem stalks aboveground and promote deep underground root rooting.
Second, the whole process of cultivation
Good fertilizers and root-raising products can not only control wang but also have a strong effect.
Liu Zhenqiang: water control + fruit control Wang double insurance
Regarding the control of the eggplant, the approach of Liu Zhenzhuang Liu Zhenqiang of Wenjia Street in Shouguang City, Shandong Province, is different from others.
Many people choose the night temperature control, this method is good, but too strenuous, Liu master is the use of water control and fruit control methods, although excessive water control is not good, but moderate water control is one of the best ways to control the tree. Prosperous vegetables appear. Avoid flooding. To pour small water, it is generally sufficient to pour half a ditch at one time, and at the same time, it is necessary to dig out after watering. At the same time, for those plants that are prosperous and serious, they can pinch their heads and promote their growth.
If the above two methods are used, and there are individual plants prosperous, then this plant's door will not be removed as soon as the eggplant first, should be eggplant eggplant size, three eggplant flowers and then removed. You can also twist the door and eggplant properly until the rapid expansion of the eggplant when the removal of the door eggplant, to control the prosperous goal.
Zhangying Zhang: Accurate drug control skillfully promotes
Zhang Heyuan, Hekou Township, Heguan Town, Qingzhou City, Shandong Province used drug control to control the length of the zucchini and achieved good results.
Simply using drug control, the required method must be precise, especially when the temperature changes, the amount of drugs to be changed, such as when the temperature of the squash shed at 25-26 °C, can be used 15% paclobutrazol 9g against 15kg of water, evenly sprayed in the 550- The middle and lower leaves of 600 plants must not be sprayed on the middle and upper leaves of the plants; if the middle and upper leaves are to be sprayed, the amount of paclobutrazol should be reduced to 4 grams, and the liquid should be sprayed directly at the growing point of the plants. on. Under normal circumstances, the optimum concentration of the middle and lower leaves of the sprayed plants is: in the early spring when the shelf temperature is around 20°C, the amount is 7g against a bucket of water; when the shelf temperature reaches 30°C, the dosage can be increased. As large as 11g against a bucket of water. Change the concentration of the pharmaceutical agent and adjust it in time to control the growth and promote the strong effect. â€
Blue Spirulina Pigment Phycocyanin Powder is natural light blue colorant extracted from blue-green algea ( Spirulina ) . It`s good water soluble , Alcohol and lipid insoluble . Spirulina Phycocyanin accounts for as much as 20% protein and attaches itself to photosynthesizing membranes, also it`s anti-inflammatory and antioxidant. It`s an accessory pigment to chlorophyll .It's derived from C-phycocyanin and allophycocyanin which have fluoresent properties that are valuable to research in immune assay kits.Spirulina Phycocyanin is selective about which cells it attaches to making it simple to track down.
Phycocyanin is a pigment-protein complex from the light-harvesting phycobiliprotein family, along with allophycocyaninand phycoerythrin.It is an accessory pigment to chlorophyll. All phycobiliproteins are water-soluble, so they cannot exist within the membrane like carotenoids can. Instead, phycobiliproteins aggregate to form clusters that adhere to the membrane called phycobilisomes. Phycocyanin is a characteristic light blue color, absorbing orange and red light, particularly near 620 nm (depending on which specific type it is), and emits fluorescence at about 650 nm (also depending on which type it is). Allophycocyanin absorbs and emits at longer wavelengths than phycocyanin C or phycocyanin R. Phycocyanins are found in Cyanobacteria (previously called blue-green algae). Phycobiliproteins have fluorescent properties that are used in immunoassay kits. Phycocyanin is from the Greek phyco meaning "algae" andcyanin is from the English word "cyan", which conventionally means a shade of blue-green (close to "aqua") and is derived from the Greek "kyanos" which means a somewhat different color: "dark blue". The product phycocyanin, produced by Aphanizomenon flos-aquae and spirulina, is for example used in the food and beverage industry as the natural coloring agent 'Lina Blue' and is found in sweets and ice cream.
