Seedling growing bed constructed with water-fertilizer carrier and diskless seedling growing method

Abstract

The invention discloses a seedling growing bed constructed with a water-fertilizer carrier and a diskless seedling growing method. The seedling growing bed constructed with the water-fertilizer carrier comprises a woven fabric layer, a water-fertilizer carrier layer, a breathable layer and a matrix layer which are sequentially arranged from bottom to top. Seeds are warp-spun in the matrix layer, or seeds are arranged between the breathable layer and the matrix layer. The thickness of the water-fertilizer carrier layer ranges from 1 cm to 5 cm, and / or the thickness of the matrix layer ranges from 1 cm to 5 cm. According to the seedling growing bed, by means of multilayer structural design in the seedling growing bed, a warehouse function of storing water and fertilizer is provided for seedlings, the water and the fertilizer are supplied effectively in time, and strong upland crop seedlings can be cultivated.

Description

technical field [0001] The invention relates to a seedling raising bed constructed by water and fertilizer carriers and a method for raising seedlings without a tray, belonging to the field of dry grain crop cultivation. Background technique [0002] Standardized seedling raising technology is the key to realizing rice machine transplanting. Plastic disk (floppy disk or hard disk) seedling raising and double-film seedling raising have become two common machine-transplanting seedling raising methods because of their simple operation and good feasibility. However, there are also some practical problems. Plastic trays (floppy disks or hard disks) need to be placed manually before planting, and special seedling trays need to be recovered and cleaned after machine insertion, and a storage site for special seedling trays is required. In addition, the special seedling tray is only used 1-2 times a year, with low utilization rate and high cost. Compared with plastic tray seedlings,...

AI Technical Summary

Problems solved by technology

Dry fine soil and mud are also used as rice seedling bed soil, which are distinguished according to their water content. Therefore, there are two different seedling raising methods: dry fine soil and mud seedling cultivation, dry fine soil and mud seedling cultivation The root system of the rice seedlings cultivated by the method is well integrated with the soil, and the seedlings turn green quickly after being machine-planted in the field, and the seedling raising effect is good, but the mud seedlings need to be manually or machine-made mud in the paddy field and plated, and stones should be removed and rice harvested when making the mud. The labor intensity and labor cost are high to remove the grains, weeds and other sundries left behind.

For raising seedlings in dry fine soil, it is necessary to take the soil from the plow layer of the paddy field before winter, crush the soil after drying, sieve out stones and weeds, and mix it with fertilizer for storage. Many, high labor costs, and require a special storage place

In addition, it is difficult to control the dry humidity of the seedlings raised in dry fine soil and mud. If it rains before machine transplanting, the seedlings will rot easily. Porosity increase

The use of commercial substrates for seedling cultivation is lighter than mud and dry fine soil methods, and can be used in assembly line operations in seedling cultivation factories. The operation is relatively simple, but the physical and chemical costs of seedling cultivation substrates are relatively high

In addition, the matrix contains chemical substances such as fertilizers and pesticides when growing seedlings in the matrix, which requires strict management of water in the seedling fields. Too much or too little water can easily cause dead seedlings, and the appropriate amount of water is affected by changes in temperature. Rotten seedlings and dead seedlings often occur due to poor handling

Straw powder overcomes the disadvantage of high cost of raising seedlings on commercial substrates, but it is more difficult to mix fertilizers, adjust acidity, and prevent and control diseases and insect pests, which may easily cause damage to seedlings and rotten seedlings

[0004] Regardless of whether it is plastic disk (floppy disk or hard disk) seedling cultivation or double-film diskless seedling cultivation, and regardless of substrate or mud, all the above-mentioned seedling raising methods require strict management of water and fertilizers throughout the seedling raising process, which is time-consuming and labor-intensive. Risks of irregular seedling emergence, dead seedlings, etc. due to improper management
