One of the scientific fertilization is the early recovery of nitrogen fertilizer. Early delivery of throwing planted early rice occurs early, and fertilizer should be grabbed for 3~5 days after throwing planting. The amount of mu is about 7.5 kg of urea. The second is to increase potassium fertilizer. The period from spike differentiation to heading is the period when most of rice has absorbed fertilizer, especially the demand for potash fertilizer is large. During this period, 8 kg of potassium chloride is used per acre.
Timely seedling control and seedling planting early rice has the characteristics of fulminant occurrence of early delivery and fast tillering. The timely completion of the drainage and drying of the field work is done so that the seedlings reach the unequal time (about 20 days after throwing) and the seedlings reach unequal time (mu. The total number of seedlings reached 350,000 or so). When the sun was applied to the fields, cracks were observed. The feet did not sag, and when combined with potash fertilizer and uniconazole, the length of the internodes was increased and internode roughness was increased.
Sprinkle Uniconazole with 5% Uniconazole EC 30 ml, add 0.5 kg of water to the mother liquor, and then mix in 5 to 10 kg of dry fine yellow earth ash. After mixing well, spread the whole field evenly. Under normal circumstances, the application of uniconazole does not generally appear lodging.
In the middle and late interstitial irrigation, water management in the middle and later stages should be based on the basting of the good fields, and the shallow water should be grounded during the young spike differentiation to the heading and flowering stage, and then be rehydrated after naturally falling dry. During the grouting period, dry and wet-dry gaps were used to irrigate the soil. Shallow water was poured from 3 to 7 days and dried naturally until the field ridge was hard but there were no obvious cracks.
Using the latest computer graphics and image technology, the patient is placed in a virtual environment, by picking technology, make the person can see on the screen or take the form of virtual figure, according to the change of scene and in the screen prompt to do all kinds of action, to keep the screen scene pattern continues, until finally complete the training goals.
