White field management and harvesting techniques
1, field management
(1) Top-dressing: After the new planting of the spring planted white plants for about 10 days, the first top-dressing was performed, and 500 kg of human waste was applied per 667 square meters (1 mu). The new growth period of the autumn planting is short. The cultivation period is usually 10 to 15 days after planting. The first time is 1500 to 2000 kg per person per 667 square meters (1 acre); the second top dressing is carried out before delivery. In order to increase effective delivery, 1,000 to 1,500 kg of urine is applied per 667 square meters (1 acre); the third topdressing is carried out during the pregnancy and expectoration period. 2500-3000 kilograms, to promote the expansion of pale white.
(2) Water management: The water layer management adopts shallow and shallow irrigation principles. After planting, the water layer should be kept 3 to 5 cm deep in the early stage of delivery to promote the occurrence of rooting and effective tilling; deepen the water layer to 15 cm later in the tillering stage to suppress ineffective delivery and promote pregnancy and tenderness so that the whiteness is tender, but the water depth should not exceed 2/3 of the height of the main stem; when the temperature in midsummer exceeds 35°C, appropriate deep irrigation should be performed and regular precipitation should be used to reduce the temperature to prevent anaerobic root cause of rot. Keep deep water during harvest, but do not exceed the degree of blindness. If it is too deep, it will result in a decrease in production; during the winter, it should be kept in a shallow or wet state of 3 to 5 cm.
During the growing period, in order to facilitate the cultivation and weeding, the fields should be drained on the 4th to the 5th, the 12th to the 14th, and the 18th to the 20th days after the planting. In the first and second drainages of the open field, cultivators should be cultivated to promote hair rooting and childbirth.
(3) Stripping of yellow leaves: During the period from major heat to early autumn, the yellow leaves at the base of the plants are stripped to facilitate ventilation and light transmission. Generally, the leaves are stripped 1 or 2 times. The peeled yellow leaves stepped into the water as fertilizer.
(4) Miao Miao, Filling Piers, and Dredging Piers: The newly planted Pak Pak Tin should be timely replanted; the old Pak Tin field should be dug out after the ash and mantle, and it will start to germinate in early spring and then grow old in the field. Some of the seedlings were dug up in the quack piers; the old pods were densely rooted and the tillers were crowded. During the period from clearing to trough, when the seedling height was 36 cm, the seedlings should be sparsely seedlings to remove small and dense tillers, and each seedling should remain strong. About the strain.
2, harvest
After harvesting, white rice should be harvested in time. To harvest prematurely, the meat is too tender, the flavor is not good, the yield is low, the harvest is too late, the meat is blue, the texture is rough, and the quality is deteriorated. The criteria for timely harvesting were three long pieces, the heart was shortened, the pregnancies were obviously enlarged, the leaf sheaths were separated by cohesion, and the flesh was slightly exposed, and the white eyes were shrinking like a bee-like shape. During reclamation and harvesting, the temperature is high and it is easy to grow old. As long as the middle part of the leaf sheath expands and shrinks, it should be harvested.
The harvest of white ash is generally harvested in September-November; the fall harvest time of the second quail cultivar White Spring is from late September to December, and the harvest time of the summer worm is from mid-late April to mid-June. The white maturation is not regular and is harvested every 4 to 5 days for a total of 4 to 5 times. The output per 667 square meters (1 acre) includes 1000 to 1300 kg of shell clams and 600 to 780 kg of maize.
