Description
Technical Field
The invention relates to a silk seedling type rice mechanical transplanting strong seedling matrix and a preparation method of organic mixed filling components in the matrix, belonging to the technical field of rice cultivation.
Background
With the improvement of living standard, people have increasingly increased demand for high-quality rice, and the planting demand of silk seedling type high-quality rice is also increasing. However, compared with high-yield high-quality rice, the silk seedling type high-quality rice is relatively tender, the stems are relatively soft, the plants are high and dense, and the lodging risk is relatively high. In the current production, although the traditional slurry seedling raising can enable the roots of the seedlings after mechanical transplanting to be quickly fused with soil and green turning to be quick, the slurry seedling raising needs a large amount of slurry, which not only consumes labor, but also needs to apply more chemical fertilizers and pesticides, and causes soil pollution and water pollution. But also can generate tender and tender spindly seedlings, and the seedlings are often thin and weak in stems, long and thin in leaves and underdeveloped in root systems. Strong rice seedlings require strong stems and leaves, moderate internode spacing and developed root system.
In addition, the organic planting high-quality characteristics of the silk seedling type rice are obvious, and the planting of the chemical fertilizer is not obvious. The silk seedling type rice is not resistant to low temperature, the rice is not too early to be grown early and not too late to be grown late when the rice is raised, otherwise the rice is more easily frozen in the seedling stage and the later stage. The cultivation of strong seedlings with suitable age is an important link for high yield of silk seedling type rice and is also an important technology for implementing large-scale machine transplanting. At present, some rice substrates are obtained by mixing fermented straws and animal wastes with peat and the like, but the peat is mainly distributed in the northeast and southwest of China, so that the exploitation and the transportation are inconvenient, the peat belongs to non-renewable resources, and the environment is greatly damaged by exploitation behaviors. In addition, the straws contain a large amount of organic matters, nitrogen, phosphorus, potassium and trace elements, and are important organic fertilizer sources for agricultural production. For a long time, the utilization rate of the straws is low in China, and farmers burn a large amount of straws, so that the waste of the straws and the air pollution are caused. A large amount of straws are discarded and incinerated every year, which not only causes serious environmental pollution, but also causes a large amount of waste of organic matters and nutrient resources.
