Medium-term paddy field technical advice
First, the current situation According to a typical field survey conducted on July 18, the machine inserts rice leaves with a leaf age of 7.81 to 10.5 leaves, which is similar to the same period of last year. The seedlings per acre have an average of 273,400, an average of 273,000, which is 42,000 less than the same period of last year. The average leaf age of direct-seeded rice was 8.9 leaves, which was 0.2 leaf more than that of last year; the average seedling volume of seedlings per mu was 382,000, which was 25,000 less than last year. Second, the role of the field 1, ventilation root. By putting aside the fields, the condition of soil ventilation can be effectively improved, the number of white roots can be increased, roots can be pulled down, and root activity can be increased. In particular, the total amount of straw returned to the field, through the field can reduce the toxic gases in the soil. 2. Inhibit invalid childbirth. After field pruning, the absorption of nutrients by roots is reduced, which can effectively inhibit the growth of various organs in the shoots, especially the occurrence of ineffective tillers, which helps to improve the tillering success rate, shorten the basal internode length, and improve plant lodging resistance. 3, reduce pests and diseases. After field pruning, leaf color fades, leaves firm, leaves and internodes shorter, the group's light transmittance improved, making the stems thick and healthy, anti-stress strength, can reduce the incidence of sheath blight. Third, the principle of holding land The principle of putting aside the fields: When the seedlings are not equal to the time, the seedlings are not equal. 1, when the seedlings are not equal. At the critical leaf stage or slightly before the effective tillering, as long as the total number of stems reaches 85-90% of the expected number of panicles (about 13-14 rootstocks per hole), they should be immediately drained. 2, from time to time seedlings. To shake the childbirth, invalid childbirth leaf age, regardless of the number of stems should be drained field. According to meteorological forecast, from 21st to the end of the month, mainly rainy weather, more than 90% of the total number of seedlings or seedlings of Tatsuki, from July to the end of July 25, no later than the end of July, To drain the water, do the rain and stop the dry land, until the leaf color fading and yellow, ensure that the jointing rice during the jointing stage is controlled 1.4 to 1.6 times the spike number seedlings, and the direct seeding rice is controlled at the spike number 1.5 to 1.7. Times. Fourth, field technology 1, open ditch. According to the size of the plot, open a cross-shaped or well-shaped high yield channel. 2, the number of times. Depending on the soil quality of Miao, it is sufficient to plant seedlings early and the field that grows stronger should be put aside early, and appropriate weight should be given. On the contrary, it should be postponed, put on hold, and put on multiple occasions. Lixia River has poor soil permeability and should be put off early. 3, lightly. At present, the seedlings per acre are significantly less than last year, and they must be maintained in a moderate manner to prevent over-stocking, resulting in insufficient panicles. Shelter method: Take drainage or dry naturally to achieve a solid soil, the field does not sink into the foot, white roots appear in the field, and the topsoil is cracked. 4, time. The period from the present to the end of the leafage at the end of 3 leaves (usually at the end of July and early August) is a suitable shelf life. 5, seedlings. In the field period, it is generally not advisable to use fertilizer when it is enough for seedling plots, but the plots with insufficient number of seedlings need to be put on a fat stand (about 10 pounds of urea per mu), put on hold, and hold lightly.
