“Anxi Early Pipa White†is the main variety of Longbai Town of Anxi County, mainly distributed in Guiyao, Guilin, Longmei and other villages. With a long history of planting white rice, Changbai has become the main agricultural economic income and pillar industry in the Changbai planting village. The production management process was implemented and the “five-unified†management model was implemented, namely: unified land preparation, unified fertilization, unified pest control, unified water management, and unified acquisition of sales. To this end, each of the major producing villages in the township has formed a one-stop form of production and sales. It has played an active role in promoting agricultural efficiency and increasing farmers' income. The main technical measures for high-yielding, high-yielding cultivation of white rice are now described as follows:
1. Site preparation base fertilizer
The ploughing immediately after the harvest was completed in late October in order to make the land mature.
Apply basal fertilizer before rotavating in spring. Basal fertilizer is dominated by organic fertilizer and 1500-2000 kg of pig manure is applied. The plots were plowed and kept in shallow water. Prior to planting, ammonium bicarbonate and superphosphate were used as base fertilizer.
2, timely planting reasonable dense planting
White planting time is spring time. In mid-February, when the seedlings grow 20 centimeters long, they will begin transplanting. Before transplanting, they will remove the plants that have been over-prosperous in the farmland and will not lead to the development of male fleas. When transplanting, each small pier should have 3-5 new seedlings, and must have old mossy pipe, with the digging, with the points, with the planting. If the plant height exceeds 50 centimeters, the excess can be divided to reduce the evaporation of water, which is conducive to early survival.
White planting spacing 80100 cm, planted 800 acres per acre, the number of basic seedlings about 3000. Planting depth is generally 10 cm old root embedded in the soil, the old plant on the upper ground is appropriate, transplanting suitable for cloudy days or sunny after 15 o'clock, favorable survival.
3, field management
(1) Top dressing: After the planting, the seedling fertilizer, the tiller fertilizer and the pregnant manure fertilizer are applied. The principle of mastering is to promote, control, and promote afterwards.
After the return of spring, about 7-10 days after transplanting, the seedlings will be applied once according to the conditions of the base fertilizer and the seedlings. The first time after the top dressing, the fertilizer shall be applied once every 10 days or so and the compound fertilizer 60-100 Jin, so that the growth of white sturdy and promote delivery; plant start pregnancy ( (flat stalk period), topdressing topdressing in a timely manner to promote fleshy stem stalk hypertrophy, increase production, Mushi perishable manure or human waste 4000-6000 pounds.
(2) Irrigation: Waterlogging can not be cut off during the whole growth period. The level of water level is adjusted with different stages of growth. According to the principles of shallow-deep-lightness, we should master shallow water transplanting, suitable water live seedlings, thin water to promote flooding, deep water, live water, and shallow water harvest.
When planting, shallow water of 3-4 centimeters is appropriate to improve the temperature in early spring, and to promote survival to green; after growing, it can be deepened to 6-7 centimeters, and as the plant grows, it gradually deepens to a water level of 18-20 centimeters. But can not be super-leaf pillow (eyes white); harvesting shallow water harvest.
(3) Weeding: weeding in paddy field before planting eucalyptus. Afterwards, we need to manually remove the grass that occurs in the field, usually 2-3 times.
(4) Peeling leaves and pulling yellow leaves: At the late stage of planting, the old leaves are removed to allow ventilation between the plants and the plants, so as to facilitate plant pregnancies.
(5) Prevention and control of pests and diseases: attention should be paid to the prevention and control of diseases and pests such as white rust, peony leaf spot, fly locust, and roundworm. The main use of agricultural control, combined with chemical control when necessary. The control of planthoppers should be in the young nymph stage. Pesticides can be sprayed with imidacloprid and buprofezin. The control of locusts should be sprayed with insecticidal water at the peak of hatching. The disease should be controlled at the early stage of the disease. At that time, it is necessary to pay close attention to medication, pesticides may be difenoconazole, thiophanate-methyl, carbendazim, and other azole. In addition, the use of bactericidal agents in the pre-pregnancy and pre-pregnancy period should be used with caution to prevent killing of smut fungus and produce infertile males. Any pesticides should be banned for 10 days before harvesting.
4, harvest
The external appearance index of P. albicans is that the base of the pseudo-stem of a single plant stem is significantly enlarged, and the tightly-wrapped leaf sheath is about to be split or cracked. Harvesting is too early to affect production; if it is not overdue, it will reduce quality and lose its value.
