In recent years, with the development of rice machine insertion, the area of ​​machine transplanting has expanded rapidly, and machine transplanting has greatly replaced artificial transplanting, solving the contradiction of delaying the season due to insufficient labor. In order to further save the cost of machine-planting rice and improve the efficiency of grain production, the agricultural technology experts of Qingyuan County Agricultural Bureau have experienced hard-boiled seedlings in Shanghai and other places. This year, the Fumin Food Professional Cooperative in Zhukou Town carried out a demonstration of rice seedling transplanting in hard soil. The indoor cement site replaces the traditional field nursery and cultivates a strong machine that fits the machine. It has achieved success. From the perspective of production practice, the rice seedling hard seedling raising technology fully complies with the development of rice production to save labor, simplifying the development of cost-saving and efficiency, and is suitable for large-scale large-area seedlings in factories. Hard seedlings have four major advantages:
(1) Save a lot of breeding fields. Traditional breeding must have a dedicated field, and hard seedlings do not require dedicated fields in the room, which can save a lot of cultivated land resources to grow crops.
(2) Save a lot of manpower. Putian nursery, not only need to plough, rotary tillage, do sputum, but also operate in paddy fields, labor intensity, low potency, and it is difficult to make the field to level, no weeds, no residue, affecting seedling growth. The cement site is relatively flat, used for rice seedlings, not only reduces the labor intensity of seedlings, saves the seedling labor, improves the effectiveness, and the seedling tray is not stained after transplanting the seedlings, and can be collected without manual washing.
(3) Saving a lot of water resources. Putian nursery needs irrigation and other water, but more than 90% of the irrigation water is lost through the soil, and irrigation also consumes electricity resources. Hard seedlings consume very little water.
(4) Factoryized seedlings can be implemented. Hard seedlings can be raised indoors, and can be factory-cultured to avoid damage to seedlings caused by abnormal weather and improve seedling quality and seedling success rate.
