A kind of seedling raising tray and sowing method thereof

Abstract

The invention discloses a seedling cultivation hole tray which comprises a growth tray used for containing a seedling cultivation substrate and a covering tray located above the growth tray to correspondingly match with the growth tray and used for sowing, wherein the growth tray is composed of an array which are formed by multiple growth holes; the covering tray is composed of an array which is formed by multiple covering hole grooves; the growth holes and the covering hole grooves correspondingly match with each other in the aspects of number and position. The seedling cultivation hole tray simplifies multiple procedures of seedling cultivation and sowing links of the hole tray, realizes streamlined sowing technology and efficient operation, reduces sowing employment rate and also realizes digital quantitative control and standard management of the sowing height and the covering depth, and further improves seedling cultivation quality. In addition, the invention also provides a method for seedling cultivation and sowing by utilizing the seedling cultivation hole tray, which can realize efficient sowing, simple operation and strong operability.

Description

technical field [0001] The invention relates to the technical field of crop seedling raising and seedling breeding, in particular to a seedling raising plug and a sowing method thereof. Background technique [0002] As a new technology for specialized cultivation and production of commercial seedlings in plug trays, seedling cultivation carriers are mostly light loose substrates with good water and fertilizer retention properties, such as peat, vermiculite, crushed fruit chips, organic humus, etc. One or more Therefore, the amount of raw materials can be reduced to meet the nutrient and water for seedlings, and light and simple seedlings can be implemented; precision sowing in the holes of the plug trays can realize one seed for one seedling, which greatly saves the use of seeds; it also saves seedlings. Intensify and factoryize management. At the same time, the labor intensity is reduced during transplanting, which is beneficial to mechanized operations. It has the charac...

AI Technical Summary

Problems solved by technology

However, there are also some deficiencies. The main ones are that the sowing is complicated and extensive, and requires repeated drilling, spotting and covering. Filling is difficult and time-consuming, not only time-consuming, but also unable to achieve uniform coverage thickness and seeding depth, and it is impossible to accurately achieve standardization of coverage depth

The second is that the emergence of the plugs is inconsistent, because the uniform thickness and sowing depth cannot be guaranteed, which affects the response and absorption of the seeds to temperature and water, so that there are differences in the emergence speed, which in turn affects the growth management of the seedlings. This is why plug seedlings generally have up to 20-30% cavitation rate

In addition, the water outlet hole of the ordinary hole tray is set at the bottom of the hole hole, so that for crops with strong growth potential of the main root, such as cotton with a taproot system, the root system can easily penetrate the bottom of the hole tray due to the seedling period of nearly 30 days; The lower tie penetrates the hole at the bottom of the tray, causing the aboveground part to elongate at the same time, which is not conducive to controlling the growth of seedlings
