Description

Technical Field

[0001] This invention belongs to the field of crop cultivation technology, specifically relating to a turmeric seedling tray, seedling substrate, and seedling method. Background Technology

[0002] Curcuma zedoaria, also known as turmeric, is a perennial herbaceous plant. Its rhizome is oval-shaped and tuberous, with cylindrical horizontal branches on the sides. The roots are slender, with the ends swelling into long oval tubers. Curcuma zedoaria has anti-tumor, antibacterial, femoral artery blood flow increasing, and anti-early pregnancy effects. Its main uses include treating qi and blood stagnation, abdominal distension and pain, abdominal masses, indigestion, amenorrhea due to blood stasis in women, and pain from falls and injuries. The tuberous root, called "green silk turmeric," has the functions of regulating qi and relieving depression, breaking up blood stasis, and relieving pain.

[0003] Currently, the cultivation of Curcuma zedoaria mainly follows the traditional extensive method, which involves directly planting the cut Curcuma zedoaria rhizomes in the natural environment. However, Curcuma zedoaria itself is not drought-tolerant, and the seedlings have poor adaptability to the environment. Therefore, water should be added in time. However, if too much water is added, it may cause the Curcuma zedoaria rhizomes to rot and deteriorate. Therefore, it is necessary to improve the method. Summary of the Invention

[0004] In view of the fact that turmeric itself is not drought-tolerant and the seedlings have poor environmental adaptability, so water should be replenished in time. However, if too much water is added, it may cause the roots and stems of turmeric to rot and deteriorate. This invention provides a turmeric seedling pot, seedling substrate and seedling method.

[0005] The technical solution adopted in this invention is as follows:

[0006] A turmeric seedling tray, wherein the seedling tray is prepared by weight from the following raw materials: 30-40 parts straw powder, 30-40 parts sawdust powder, 50-80 parts adhesive, 10-20 parts filler, and 5-8 parts additives. The adhesive includes waste plant starch and clay. The thickness of the bottom of the seedling tray is greater than the thickness of the tray wall. Several biodegradable strips are provided on the tray wall, and the thickness of the biodegradable strips is less than the thickness of the tray wall.

[0007] With this technology, the seedling trays are all made of biodegradable materials. After use, they can be directly buried in the soil. In moist soil, the trays decompose rapidly without further treatment. The nutrients in the decomposed trays can even provide nourishment for the growth of Curcuma zedoaria. After seedlings are grown in these trays, there is no need to remove them from the trays before planting, effectively avoiding damage to the roots when removing the trays. The adhesive includes expired or spoiled plant starch, which is a form of waste utilization. The combination of powder and clay achieves excellent adhesion and effectively reduces the preparation cost of seedling pots. During degradation, due to the presence of an easily degradable zone, the thickness of which is less than the thickness of the seedling pot wall, the connecting zone degrades rapidly under the pushing and decaying action of the turmeric roots, avoiding restriction on the growth of turmeric. Since the thickness of the bottom of the seedling pot is greater than the thickness of the pot wall, the degradation rate at the bottom of the seedling pot is slower, which restricts the downward growth of turmeric and prevents the turmeric from rooting too deep at harvest, making harvesting difficult.

[0008] Preferably, the sawdust powder is made from waste branches and trunks of pepper trees, the particle size of the sawdust powder is 200-300 mesh, and the filler is stone powder with a particle size of 300-400 mesh.

[0009] After adopting this technical solution, the sawdust powder is rich in cellulose and other substances, which can provide nutrients for plants after degradation. The sawdust powder made from the waste branches of pepper trees also contains antibacterial substances, which can effectively inhibit microorganisms and play a certain role in preservation. This can improve the use and storage time of seedling pots. Stone powder can effectively improve the overall hardness of seedling pots, making them easier to use and transport.

[0010] Preferably, the inner surface of the seedling pot is coated with an ethyl cellulose waterproof coating.

[0011] With this technical solution, the ethyl cellulose waterproof coating on the inner surface of the seedling pot can prevent the seedling pot from contacting the moist soil and starting to degrade. The outer surface of the seedling pot is not coated with a waterproof coating, so that the outer surface of the seedling pot comes into contact with the soil after being buried in the soil, which can make the seedling pot degrade quickly.

[0012] A seedling substrate comprising garden soil and drought and flood prevention materials.

[0013] Preferably, the seedling substrate is composed of the following raw materials in parts by weight: 100-130 parts garden soil and 10-15 parts drought and flood prevention materials.

[0014] Preferably, the drought and flood prevention material includes a water-soluble outer shell and a water-retaining material disposed inside the outer shell. The outer shell includes 50-65% main material, 20-30% antibacterial auxiliary material and 10-20% adhesive material. The water-retaining material is a dehydrated sponge made of biodegradable material.

[0015] In this technical solution, drought- and flood-resistant materials are mixed into the seedling substrate. When there is too much moisture, the outer shell will dissolve, and the dehydrated sponge will absorb water and expand, playing a water-storage role. This reduces the frequency of watering the turmeric seedlings, saving manpower. The water-storage material is a dehydrated sponge made of biodegradable material. Its porous structure can drain water and store a certain amount of water, thus playing a role in both drainage and water storage. It is made of biodegradable material and can automatically degrade after use, making it easy to dispose of and not affecting the growth of turmeric. The antibacterial additive can effectively inhibit the corrosion of the outer shell by bacteria or microorganisms in the soil, and at the same time reduce the probability of mold growth on the turmeric rhizomes, further improving the survival rate of turmeric.

[0016] Preferably, the main material is any one or a combination of two of straw and wood shavings in any proportion, the binder is any one or a combination of three of waste corn flour, waste glutinous rice flour and waste sweet potato flour, and the antibacterial additive is Sichuan pepper leaves.

[0017] After adopting this technical solution, the raw materials for preparing the shell are all plant materials, and they are all production wastes, which are low in cost and easy to popularize. After decomposition, they can also improve the nutrition of Curcuma zedoaria. The volatile substances contained in the leaves of Zanthoxylum bungeanum have a strong antibacterial and insecticidal effect.

[0018] Preferably, the garden soil is a mixture of field soil and well-rotted animal manure.

[0019] A method for cultivating turmeric seedlings includes the following steps:

[0020] Step 1: Select medium-sized, robust turmeric rhizomes with complete buds, many long tubers, and no diseases, pests, or wounds, and cut them into pieces;

[0021] Step 2: After coating the cut turmeric rhizomes with wood ash, plant them in seedling pots containing seedling substrate;

[0022] Step 3: Place the seedling pots containing the turmeric into the greenhouse for cultivation;

[0023] Step 4: After the turmeric seedlings sprout, transplant the turmeric along with the planting pot to the planting site.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. This invention changes the existing method of cultivating turmeric using an extensive approach. By first cultivating turmeric seedlings, the survival rate of turmeric can be effectively improved.

[0026] 2. The seedling trays are made of biodegradable materials and can be directly buried in the soil after use. They decompose quickly in moist soil without further treatment. The nutrients in the decomposed trays can even provide nourishment for the turmeric's growth. After planting, the turmeric seedlings do not need to be pulled out of the trays, effectively avoiding damage to the roots when removing the trays. The adhesive includes expired or spoiled inedible plant starch, representing waste utilization. The soil mixture achieves excellent adhesion and effectively reduces the preparation cost of seedling pots. During degradation, due to the presence of an easily degradable zone, the thickness of which is less than the thickness of the seedling pot wall, the connecting zone degrades rapidly under the pushing and decaying action of the turmeric roots, avoiding restriction on the growth of turmeric. Since the thickness of the bottom of the seedling pot is greater than the thickness of the pot wall, the degradation rate at the bottom of the seedling pot is slower, which restricts the downward growth of turmeric and prevents the turmeric from rooting too deep at harvest, making harvesting difficult.

[0027] 3. The water-retaining material is a dehydrated sponge made from biodegradable materials. Its porous structure allows it to drain water and store a certain amount of water, serving both drainage and water storage functions. Made from biodegradable materials, it automatically degrades after use, making it easy to dispose of and not affecting the growth of Curcuma zedoaria. The antibacterial additives effectively inhibit the corrosion of the outer shell by bacteria or microorganisms in the soil, while also reducing the chance of mold growth on the roots and stems of Curcuma zedoaria, further improving its survival rate. The raw materials used to prepare the outer shell are all plant materials and are all production waste, resulting in low cost and ease of widespread use. After decomposition, they can also improve the nutrition of Curcuma zedoaria. The volatile substances contained in the leaves of Zanthoxylum bungeanum have a strong antibacterial and insecticidal effect. Attached Figure Description
