The majority of county-level peppercorns are planted on mountain terraces, which are inconvenient in transportation, lack of fertilizer resources, and lack of water in drought. The pepper is a shallow-rooted tree species and its roots are concentrated at 20 to 40 cm. Although it is resistant to drought, the county involved nine years of drought. Therefore, "water" has become an important factor affecting the yield of pepper. Here are some of the following drought prevention measures for drought-defying Zanthoxylum bungeanum:
1. weeding The competition between weeds and prickly ash trees is very serious, and the pepper is a shallow root tree species, the surface water evaporates quickly, and the plowed flats can remove weeds, loosen the soil, and reduce the evaporation of surface water. According to observations, the tree stalks were not shaved every year, and the yellow and thin leaves of the prickly ash peppers were shriveled. The tree vigor was not ploughed for two consecutive years. The small fruiting branches began to die; Severely weak, or even losing the ability to produce results. A year can be divided into spring and autumn planes twice, combined with fertilization.
2. Leaf spray fertilizer. It sprays 3 to 4 times a year, sprays 0.3% to 0.5% urea in the early stage, and sprays 0.2% to 0.5% potassium dihydrogen phosphate in the later stage. Foliar spray fertilizer with less fertilizer effect, the effect of increasing production is obvious, with the effect of timely nutrition, enhance tree vigor, improve drought resistance.
3. Whole stilts, tree trays, digging fish scale pits and accumulating rainwater.
4. Straw mulch. The tree tray is covered with straw, weeds and other coverings, and the coverage is mainly within the canopy projection, and can also be expanded outwards appropriately. The covering thickness is 20 to 30 cm, and it is pressed with a small amount of earth to protect the earthworms.
5. Plastic film cover. Fertilize first, then loosen the soil, trim the tree disk into shallow, high-medium, shallow cups with a diameter of 80 to 180 centimeters, cover it with 1-3 square meters of plastic film (according to the size of the canopy, determine the size of the mulching film) Joints, in the vicinity of the trunk will be 3 to 6 holes in the plastic film, sealed with soil, storing natural precipitation.
6 buried grass. Straw straws are bundled into straws with a diameter of about 10 centimeters and cut into 50 centimeters long. They are buried vertically in the tree tray (vertical projection of the canopy). Each tree is digging 4 to 6 pieces. The distribution is even and the height of the straw is slightly higher than the top. ground.
7. Artificial water. In a special year, there is no rain on consecutive sunny days, and the leaves begin to nap in the afternoon and stretch in the morning. In this case, water must be replenished manually. Artificial water is not only time-consuming, but also time-consuming. Therefore, it is necessary to use limited water to maximize its use. A two-inch iron tube can be used to weld a "T"-shaped structure, with a crossbar length of 50 cm and a vertical rod length of 100 cm. The lower end of the nozzle is polished with a grinding wheel to be thinner. One scale for every 10 cm, and a small mouth for 1 cm at 20 cm, is convenient for earth-fetching and the labor-saving “drilling device†is used. Use a drill to hit 3 to 6 eyes in the root of pepper (according to the size of the canopy, determine the number of drills). The distance from the neck to the neck is 40 to 50 cm and the depth is 20 cm. Fill each eye with water to let it infiltrate naturally. The special drought can be re-irrigated once and finally buried back with soil. Because the water can diffuse freely and reach the roots smoothly, it does not waste a single drop of water, so that the water can maximize its effect and ensure that the prickly ash tree spends its extremely dry years.
8. Use old cellars. There are some abandoned water cellars in the ground, which can be restored by intercepting surface runoff in the rainy season or arranging interception of shallow water. The water cellar is a small mouth, large belly, can hold 20 to 40 cubic meters of water, sealed mouth, water cellar evaporation is small, non-leakage, due to dark storage, water quality remained unchanged for a long time.
9. Set up a simple water storage bag. Its structure is simple and its investment is small. In a thick layer of highland or hillside terraced pepper trees, dig 1 to 2 meters in depth, 1 to 2 meters in depth, and 30 to 50 meters in length. Use iron shovels to sparge the walls and the bottom (no puncture) Plastic film thing), buy tube-shaped plastic film (bag thickness 0.88 mm, tube circumference size equal to 2 times the groove widening, 3 grooves deeper than the groove length), place two in the groove, rainy season land After the surface runoff or with a shallow flow or with a water storage bag at the water lift station, use a rope to tie the two ends, and then cover the roof with a cement board or use a wooden rod and straw roof and cover the soil to prevent freezing. This will prevent light from accumulating for a long time. change.
Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to waste from fish waste, duck manure, or normal nutrients.
