Embodiment Construction
[0016] 1. Cultivate strong seedlings of the right age
[0017] (1) Cultivate bed soil and prepare seedlings.
[0018] In the first ten days of February, choose vegetable garden soil, cultivated dry land or surface soil (0-20cm) of paddy field for fertilization, and evenly apply 2000kg / 667m of decomposed human and animal manure 2 , and nitrogen, phosphorus, potassium compound fertilizer 40kg~50kg / hm 2 , after spreading evenly, use the rotary tiller for 2-3 times of continuous operation; the soil maturation process should be about 20-30 days, take about 15cm of surface soil for composting, and keep the water content of the soil mound at 10%-15%. range, the fine soil particle size should be below 5mm. After sieving, press the seedling bed soil of the floppy disk seedling raising machine for every 667m 2 Daejeon 18-20 pieces of floppy disks, each floppy disk prepares 4.0-4.5kg of qualified bed soil; double-film seedling raising machine inserts seedling bed soil per 667m 2 Prep...

The invention relates to a machine-transplanted rice cultivation method, in particular to a machine-transplanted rice cultivation method with the balanced fertilization function. According to the machine-transplanted rice cultivation method with the balanced fertilization function, a nitrogenous fertilizer application method with the process of promotion in the early period, control in the middle period and stabilization in the later period is applied, the application amount of tillering fertilizer is reduced, the ratio of the tillering fertilizer accounting for the total nitrogen application rate is controlled to be about 5%, the requirement that early tillering in the early period of machine-transplanted rice seedlings happens, and high-yield groups are formed early is met, the number of the groups in the middle period is effectively controlled, effective tillering and ear bearing are promoted, the maximum leaf area index ranges from 7.5 to 8.0, the effective leaf area in the later period decreases slowly, premature senescence of the groups is effectively avoided, and the yield structure of rice is optimized. Compared with an existing machine-transplanted seedlings, the seedling age is controlled to be about 18d through the technology, the seedling height is controlled to range from 13 cm to 18 cm, the leaf age is controlled to range from 3.2 to 4.0, the prolonged time of the seedling age is smaller than or equal to 25d, and the leaf age is smaller than or equal to 4.2. Compared with the prior art, after the technology is applied, the seedlings are orderly, the difference between plant individuals is small, vain growth does not happen, yellowing does not happen, and growth is exuberant.
Description
technical field [0001] The invention relates to a machine-transplanted rice cultivation method, in particular to a machine-transplanted rice cultivation method with balanced fertilization. Background technique [0002] The existing machine-transplanted rice blanket-like seedling technology has problems such as large seeding rate, poor seedling quality, small seedling age elasticity, long seedling slowing period in the field, and uneven tillering at different stages, which directly affects the balance of rice panicle formation in the later stage. . Due to the high planting density of blanket-like seedlings, there have been repeated applications of tillering fertilizers and excessive tillering fertilizers in the field of machine-transplanted fertilizers for many years, for example: "How to apply rice well" published by China Agricultural Information Network In the article "Three Fertilizers", it is mentioned that the amount of tillering fertilizer accounts for 50-60% of the t...
