1. Deep plowing and applying base fertilizer
Generally 400 kg of land per mu, Shi Nongjia about 10,000 pounds, ammonium bicarbonate 20 to 50 kg, 50 kg of potassium phosphate can be. Experts said: "Can not ignore the soil fertilizer by fertilizer, ignore the basic fertilizer by top dressing, ignore the phosphorus fertilizer by nitrogen fertilizer. Phosphorus fertilizer can promote early maturation, control of invalid leaves. On the basis of the deep fertilization, 耙耘 耙耘 耙耘 耙 耙 耙, 耙 使 使 使 使 使 使 使 使 使 使 使In order to eliminate the soil pests (eg earthworms, golden needle beetles, ground tigers, etc.) combined with site preparation for soil disinfection, methyl flour is generally used at 2 to 3 pounds per mu.
2. Choose good seed dressing
Selection of wheat varieties suitable for the region, seeds in the sun before sowing a sun, increase the activity of the enzyme, increase the germination rate. For uncoated seeds, seed dressing should be carried out. Usually, 100 pounds of seed 3, 75% of 3911 EC or 50% of phoxim EC 2 and 2 to 7 kg of water are seeded and sown in the shade after 6 hours.
3 timely sowing reasonable close planting
What is the appropriate broadcast date? This depends on the variety, temperature, and land. Look at the variety, the spring nature of the first winter, with the description of the variety as the standard, the first few leaves and more leaves. Looking at the temperature, the average daily temperature of about 16°C is appropriate for winter varieties. Look at the land, thin land after the fertilizer. "White dew species are high mountains, autumn decent species, and after 10 minutes in the fall, they will return to Pingchuan." In the proper sowing period, we must seize the time and shorten the sowing date. The rational close planting is to control a reasonable group structure, to handle the contradiction between the group and the individual, the contradiction between the panicle and the panicle, and to make full use of the land and light energy to achieve high and stable production. The seeding rate depends on the requirements of the description of the wheat variety and the sowing time and soil conditions.
The ECG Machine can be divided into single channel and multi-channels (e.g., three, six, and twelve) according to a recorded signal derivative.For 1 Channel ECG, there is only one way to channel the ECG signal, and the waveform of each guide should be recorded one by one. That is, it does not reflect the changes in the conductors at the same time. There are many channels for the large channel of the multi-channel electrocardiogram machine, such as the six-way electrocardiogram machine, which has a six-way amplifier, which can reflect the simultaneous changes of the electrocardiogram of the six conductors at a certain time.
Whether you need a mobile, 3-channel ECG machine, 6-channel ECG machine, 12-channel PC ECG, you will find the proper ECG Monitor for your needs in this category.
The compatible ECG electrodes, ECG paper and Ultrasound gel also can be found in this category.
