Problems solved by technology

At present, in the practice of rice machine-transplanted seedlings, there are generally problems that the root system is not well-coiled and the seedlings are easy to scatter, especially in rainy weather, which often causes the seedlings to scatter during the process of lifting and loading, which seriously affects the efficiency of mechanical transplanting.
On the other hand, in rice machine transplanting and seedling raising, it is necessary to spread fertilizer and sow seeds in the seedling raising tray. For farmers, these operations are time-consuming and labor-intensive, and it is not easy to control the dosage, which increases the difficulty of raising seedlings.

Embodiment 1

[0019] (1) Preparation of hemp fiber film base sheet: the jute fiber of 80% and the cotton fiber of 20% are fed into the hemp processing equipment by weight percentage and the fibers are dispersed and mixed by mechanical beating, and then the rollers of the equipment are used to draw the The fibers are randomly arranged to form a fiber web, which is impregnated and bonded by starch glue, then vacuum-adsorbed and dried to form a hemp fiber film substrate with a thickness of 3mm. The hemp processing equipment adopts a well-known equipment, and the equipment name is: environmental protection The preparation device of hemp edema film, the patent number is: ZL200710303484.7;

[0020] (2) Preparation of hemp-based seed film: uniformly coat a polyvinyl alcohol aqueous solution with a mass concentration of 2%-4% on the hemp fiber film substrate, and dry the dried rice seeds at a rate of 500g / m 2 The density (determined according to the sowing rate required for seedling raising) is eve...

Embodiment 2

[0028] The method of embodiment 1 is used to manufacture rice machine-transplanted hemp-based seed film and seedling-raising, but the difference is that the raw material consists of 80% kenaf fiber and 20% cotton, and the adhesive is starch glue, and the thickness of the hemp fiber film substrate made 2mm, the rice seed density is 300g / m 2 , the seedlings raised are hybrid rice, the seedling age is 20 days, and the root system indicators of the seedlings are shown in Table 2.

Embodiment 3

[0030] Manufacture paddy rice machine transplanting seedling-raising hemp seed film and seedling-raising by the method for embodiment 2, difference is that rice seed and active ingredient are the slow-release compound fertilizer that nitrogen, phosphorus and potassium are uniformly dispersed and adhered with 3% polyvinyl alcohol aqueous solution on the hemp fiber membrane substrate, such as figure 2 As shown, the seedlings raised are hybrid rice, the age of the seedlings is 20 days, and the root system indicators of the seedlings are shown in Table 2.

Abstract

The invention discloses a rice seedling machine seedling planting diaphragm and a manufacture method of the rice seedling machine seedling planting diaphragm. By aiming at the problems that the seedling root winding effect in the rice seedling machine seedling planting is poor, the seedlings can easily get scattered, and the operation is complicated, the invention provides the rice seedling machine seedling planting hemp-base diaphragm, which consists of a hemp fiber diaphragm substrate and rice seeds fixedly carried on the substrate. The hemp fiber raw materials are subjected to loosening, scattering and mechanical stretching to form a net, then, biodegradable bonding agents are adopted for bonding, baking is carried out, the hemp fiber diaphragm substrate is formed, and next, the rice seeds are uniformly scattered and pasted on the hemp fiber diaphragm substrate through the biodegradable bonding agents. When the rice seedling machine seedling planting hemp-base diaphragm provided by the invention is adopted, the seedling culture operation can be greatly simplified, farmers can realize the seedling culture without seeding, in addition, the seedling root system winding effect can be obviously promoted, the winding force is improved, seedlings conforming to the machine seeding requirements are formed, meanwhile, because the seedling quality is improved, the green returning speed of the seedlings after the machine seedling planting is high, the tillering effect is good, the rice yield is obviously improved, and good economic benefits are realized.

Description

technical field [0001] The invention belongs to the technical field of rice seedling raising by machine, and in particular relates to a rice seedling raising membrane and a manufacturing method thereof. Background technique [0002] At present, rectangular plastic seedling trays (usually 58cm×28cm) are generally used in rice machine transplanting and seedling raising in my country, and there are two common forms of floppy disk and hard disk. When this kind of seedling tray is used for seedling cultivation, 1.5-3cm thick seedling soil is placed in the seedling tray to form a seedbed, and rice seeds are randomly sown on the seedbed at high density (usually 80-260g / pan), and cultivated after 15-25 days. Blanket seedlings. At present, in the practice of rice machine-transplanted seedlings, there are generally problems that the root system is not well-coiled and the seedlings are easy to scatter, especially in rainy weather, which often causes the seedlings to scatter during the...
