The row spacing is the basis, the high yield and stable yield are not required, the row spacing is 1 to 1 m1, the plant spacing is 5 or 6 mils, and the cultivation is not dense, and the ventilation and light transmission are well managed.
I. Prevention and control of blindness: timely treatment in the evening, rain and fine weather. The whole field coffers are not leaked, and the quasi-pharmaceuticals are treated together.
Second, the prevention and control of withered yellow wilting: the bottom of the organic fertilizer, the disease quickly smashed lime. Potassium fertilizer has strong resistance to leaching, and leaf fertilizer plus drugs together prevent.
3. Qiao Shi'an Fertilizer: Phosphorus and zinc organic biological fertilizer, diamine, potassium, potassium and magnesium. The roots of cotton seedlings grow well, and the seedlings do not slow down after planting.
4. Pruning innovation method: The blade has a very large effect, and it is a pity to cross it. The male branches grow to 4 leaves, and the cored fruit branches are formed. The buds are fast and strong, and the branches have buds and peaches.
Five. Chemical control four standards: one count of eight or nine leaves, the second to see four or six, three times from two fingers and half, seven times after four times.
6. Steady and skillful use of fertilizer: Phosphorus and zinc bacteria have strong roots, and the stalks of silicon, calcium and potassium are strong, and the nitrogen is less applied during the buds, and the stems are thick and thick.
Seven. Flower peach fertilizer skill: The heart is applied earlier than the leaf concave, the heart is later than the leaf convex, the leaf heart is the same length, the application of flower fertilizer is at that time, the flower fertilizer is applied after the peach fertilizer, which is separated by fifteen days.
Eight. Fertilization has a sputum: the base fertilizer should use organic fertilizer, the fertilizer fertilizer diamine nest fertilizer, bud application organic boron zinc fertilizer; 30 days after the bud fertilizer application, see the flower application of peach fertilizer, the cotton plant has a knot of six or seven peaches. Authentic application of strong peach fertilizer, 15 days after the application of peach fertilizer, the tip should be applied to cover the top fertilizer.
9. Fertilizer increase efficiency: base fertilizer bud fertilizer organic fertilizer, no fertilizer in trenching; flower fertilizer, fertilizer, inorganic fertilizer, point application, no waste, cover top fertilizer, urea, roots all absorb fertilizer; cotton whole birth In the period, fight foliar fertilizer. (Foliar fertilizer uses high-tech, targeted, and effective brand products)
Ten. The effect of dry application is obvious: the late topdressing often encounters drought, when it is time to topdress, it can't be slow. In the evening, the fertilizer is finished in the evening, the ground is white for three days, the five days are green, the seven-day branch is new, and the top autumn peach is full. Peach blossoms are more joyful.
Note: The above cultivation management is suitable for the Yangtze River Basin and the Jianghan Plain and the fertile areas of the land.
Expert Reviews:
The ten secrets have scientifically summarized and highly summarized the high-yield and practical cotton technology from the aspects of rational close planting, main pest control, remediation and scientific fertilization. The text is vivid, simple and clear, easy for farmers to memorize and guide, and is very helpful for cotton production. Meaning is worth promoting.
Digital conductivity sensors have two electrodes and four electrodes. Compared with analog conductivity sensors, digital conductivity sensors have higher accuracy and stability through digital measurement and signal processing technology. They provide accurate measurements and reduce errors due to sensor drift or interference. Digital conductivity sensors usually have a digital output interface, such as a serial communication interface (such as RS485, MODBUS, etc.) or a digital bus (such as I2C, SPI, etc.). This allows for easy connection and communication of the sensor with other devices or data acquisition systems. Daruifuno's digital conductivity sensors have built-in temperature compensation and are capable of temperature compensation. Since conductivity is closely related to temperature, the built-in temperature compensation function can provide more accurate and reliable conductivity measurement results. In addition, another advantage of the digital conductivity probe is that it is plug-and-play, internally stores calibration data, and can be calibrated offline. The material of the digital Conductivity Sensor is PPS plastic, stainless steel and titanium alloy. Users can choose the appropriate conductivity probe according to their own application.
