When does Wuding tobacco leaf planting usually start and end?

Tobacco leaves are generally planted according to different local climate conditions, and are generally divided into winter tobacco, spring tobacco and summer tobacco. Winter tobacco is planted before the end of the year, spring tobacco is planted in February and March, and summer tobacco is planted around May.

Begin growing seedlings around the Grain Rain every year, that is, around April, and start harvesting in July and August, once a year.

Tobacco leaf cultivation is divided into four stages: seedling cultivation (conventional seedling cultivation, floating seedling cultivation, and direct seeding under film), transplanting, field management (seedling recovery period, vigorous period, maturity period, and harvest period), and harvesting and baking. This stage. The general yield of flue-cured tobacco per mu is between 125~175kg.

Identify the soil quality

The quality of tobacco is different, which is "determined by the atmosphere of the soil." The ancients believed: "The leaves of tobacco grown in Shatian are thin, while the leaves of tobacco grown in mountain fields are withered. The root length depends entirely on the fertility of the land, and the thick air is partly due to the richness of the soil." Anyone planted in fertile, loose, and well-drained land will grow well. Tobacco leaves grow poorly in mountains and fields, and the tobacco leaves grown in different places have different flavors. Only newly reclaimed wasteland can be replanted once, but the tops from the first year must be "leaved to the ground", otherwise they will also suffer from plague. Therefore, the land must be changed every year to grow tobacco, usually with an interval of 3 years and repeated planting once.

Sowing and raising seedlings

Before and after the winter solstice, select a fertile plot of land, hoe, dig and rake it flat, spread a layer of burnt ash about 5 minutes thick, and then sprinkle it evenly with pure fertilizer , and then sprinkle the tobacco seeds on the dusty soil. For about half a month, the seeds will germinate. Around February, they will be sprinkled again before planting. After such careful cultivation, the seedlings will be fat and easy to live.

Preparing the soil and fertilizing

Plow the ground 1 to 2 times before planting to loosen the soil and remove all weeds, and then make a border. In addition, the border should be made into a turtle-back shape to facilitate drainage, with one plant in each hole and a spacing of 2 feet between plants. Oil cakes should be put into the holes first, and then covered with a layer of plant ash. The amount of oil cake applied can be determined according to the soil fertility. After the beginning of spring, the tobacco seedlings can be transplanted after the oil cakes have decomposed under the sun and rain.

Transplanting

Before and after Grain Rain, when the seedlings have 3 to 5 leaves and are about 4 to 5 inches high, they can be transplanted on rainy days. Before planting, the roots of the seedlings should be in the soil, not all on the oil cake. If it is sunny, you can water the seedlings with a fertilizer-to-water ratio of 1:9 for 3 consecutive days until the seedlings are alive.
