Pepper pepper cultivation technology points A seed storage and germination: Zanthoxylum seed hard, oily and difficult to absorb water, germination is more difficult, must be degreasing treatment. If it is autumn sowing, the seeds can be placed in alkaline water (1 kg of seeds with 25 grams of alkaline surface, add water to submerge the seeds for degrees), soak for 2 days, wash seed coat oil, remove and then sowing. For spring sowing, it needs to be properly stored to prevent evaporation of winter oil and reduce germination. Storage methods vary from place to place. There are mainly the following types of storage methods:
1. Storage of vegetation ash: In the autumn, 3-5 times as much as the seed of the plant ash is mixed with water, stored, and often kept moist.
2. Mud cake collection: Mix the seed with sandy loam, add water and mix it into a thick mud (or add some cow dung) to make a mud cake, put it in a dry and ventilated place after being dried, and use it as a seed for next spring.
3. Cylinder storage: Pour the dried fresh seeds into a jar, cover it, put it in a cool, dry room, and maintain the ability to germinate. Generally, 15 to 20 days before sowing, the stored seeds are removed from debris and placed 30 cm above the sun, sprinkled with water and covered with a plastic film, once every 1-2 days, until most of the seeds are germinating. sowing.
Second, sowing and fertilizer management: autumn sowing in the soil before freezing, spring sowing in general in mid-March to early April, the surface temperature of 10 cm when the soil temperature is appropriate to 8-10 °C. The basal fertilizer should be applied to the nursery place, and the stalks should be smashed and irrigated with water after deep plowing. Drilling, spacing 20-25 cm, covering the soil 1 cm thick, and then cover the surface of a thin layer of grass or plastic mulch to keep the surface moist, remove the cover after emergence. Seeding rate of 4-16 kg per mu. Seedling height 4-5 cm seedlings, spacing 10-15 cm, 6-7 months per acre urea
Application of 10 kg, irrigation after application, timely cultivator weeding, rainy season pay attention to row of oysters, generally when the seedling height up to 70-100 cm. Rational fertilization can significantly increase production. The basal application of basal glycogen can be applied in autumn and autumn. The best fruit to be harvested after the autumn fruit is harvested. Each culm is circulated with 25 kg or so of compost, pay attention to fertilizer and soil, and apply water after application. Top dressing twice a year. The first time in the germination stage, it can promote the growth of the shoot, increase the fruit setting rate, and promote the growth of young fruit; after the second harvest, it can also be combined with the autumn application of base fertilizer, which is conducive to flower bud differentiation and root growth, and improves the leaf growth. The function of increasing the nutrient storage of the tree plays an important role in ensuring the increase of production in the following year. The top-dressing tree of the top-dressing tree is 0.25-0.5 kg of urea per time, and timely irrigation after top-dressing. In drought years in Gansu Province, it is necessary to pay attention to appropriate irrigation in April, May and June to ensure the growth of the shoots and the development of young fruit to meet the need of water and prevent serious fruit drop. Pepper is not resistant to maggots, and it is necessary to pay attention to drainage and flood prevention during the rainy season.
Third, the plastic trim: pepper hi light, strong branching, strong results mother bearing the ability to produce, through pruning, concentrated nutrition, improve lighting to high yield stable production.
After the planting, it shall be dried at 40-50 cm. When the winter cuts, the lower branches of the main trunk shall be sparsely removed, and the upper 3-6 branches shall be reserved as the main branch. The selection of one year may be completed in two years, and the central standing branch may be removed. Shortcut 1/3 of the selected main branch, cut strong buds. Leave the first side branch at a distance of 50 cm from the middle, and then leave the second and third side branches every 30-40 cm. The branches that are too dense are left weak and strong, so that the branches inside and outside the crown are not pressed and distributed evenly. Everywhere they can reach into the fist, the light is good, and it is easy to harvest. Remove excessive branches and dense branches. Retracting the results from the branches to the strong buds at the back of the branches, promotes the development of strong branches, rejuvenation, and rejuvenation through such concentrated nutrition and the pruning method of the tree vigor has a significant effect on the growth of Zhuang trees. Summer pruning is usually performed 2-3 times a year. Its main function is to wipe out or remove the over-sized and unreserved use-valued backs, leggy branches and thin and weak branches. Litchi to improve light, concentrate nutrition, increase production.
