How to fertilize super rice

Fertilization in the field. In the field of fertilization in the field, the nitrogen content of the leaves of the seedlings should be increased based on the seedlings not being placed on the leaves. The amount of base fertilizer should be increased appropriately. Rice 4 leaves and 1 heart stage began to divide, and nitrogen fertilizer was applied in 2 leaves and 1 heart stage to ensure that the nitrogen content of 4 leaves and 1 heart leaves reached about 4%. 4 days before transplanting, body fat should be applied to promote the occurrence of new roots, so that the injured seedlings are light when planted, and return to green after planting.
Fertilization in the Honda period. The super rice combination grows for about 120 days in the Honda period, and the demand for nitrogen, phosphorus and potassium in the growth process should be considered. According to the target output of 750 kg per mu, each mu needs to absorb about 11 kg of pure nitrogen, about 5 kg of phosphorus pentoxide, and about 11.5 kg of potassium oxide. Rice fertilization should supplement rice's demand for fertilizer according to soil fertility. Generally, it is necessary to apply 12-13 kg of pure nitrogen, 12 to 14 kg of potassium oxide, and 5 to 6 kg of phosphorus pentoxide. It is equivalent to standard urea of ​​26.1 to 28.3 kg, superphosphate of 41.6 to 50 kg, and potassium chloride of 20 to 23.3 kg.
In general, 6.5 kg of pure nitrogen is applied to the super rice base fertilizer, accounting for 50% of the total nitrogen fertilizer. The amount of base fertilizer applied is 50 kg of cake fertilizer or 15 to 20 organic fertilizers, plus 10 kg of urea, 30 kg of superphosphate, and 10 kg of potassium chloride. 5 to 6 days after planting, apply fertilizer. Specifically, 20 kg of compound fertilizer per acre plus 3 to 4 kg of urea, 10 kg of potassium chloride per acre. Spike fertilizer can be applied during the birth of the inverted 2 leaves. This time, the fertilization should be combined with the climate and the rice phase to apply about 10 kg of compound fertilizer. If the rice looks more robust, the leaves are straight, the length is suitable, the sun is sufficient, and it can be applied more appropriately. If the rice grows vigorously, the leaves are too long, and the rainy weather can be applied less or not.

Nuts

According to the attributes of nuts, there are national standard (GB) , German standard (Din) , international standard (ISO) , Japanese Standard (Jis) , American Standard (Astm/ansi) and other standards. Among them, GB, DGB and JGB are denoted by M (for example, M8, M16) , while the American and British systems are denoted by fractions or # (for example, 8 # , 10 # , 1/4,3/8) .

Nut Specification nut specification table is specific and detailed to unify all kinds of nuts, with the table to some of the nuts out of the specifications. There are many types of nuts, there are different materials of nuts. Each kind of nut has the different specification, each kind of screw also has it to have the mechanical performance and the function.
