Key points of transplanting and seed retention of mustard

Brassica juncea var.tumida Cruciferae plants are often hairy, bifurcated, stellate, or glandular. Flowers bisexual, usually racemes; sepals 4, separate, in two whorls; petals 4, clawed, arranged in cruciform corolla, a few apetalous (e.g., solitary, apetalous); stamens 6, in 2 whorls, outer whorls 2 shorter, inner whorls 4 longer, called tetradynamous; carpels 2, connate, ovary 1-loculed, with parietal placentation, center with pseudosepta, divided into 2 locules, each locule usually with multiple ovules. Fruit for the pod, nearly equal length and width called short pod, long for several times wide called long pod, such as shepherd's purse, solitary vegetables for short pod, cabbage, radish for long pod. There are about 350 genera and 3000 species of plants in this family, which are widely distributed all over the world. There are 90 genera and 300 species in China, most of which are in the north and northwest.

The height of the aboveground part is 60~80cm, the length of the main root is 20~30cm, and the weight of the whole plant is 2~ 4 kg. The lower part of the ground is a hypertrophic tubercle stem, with more than ten large leaves on the stem; the petiole base of the large leaves has a tubercle fleshy stem, and the obvious tubercle bulges are generally 3 to 5. Tumour stem epidermis green smooth, subcutaneous fleshy white and plump, tender and crisp texture. The tubercle stem part, namely the cabbage head, generally weighs about 0.5kg each, and the larger one is 1~1.5kg. Cooked cabbage head mixed with seasoning to eat very delicious; its boiled soup has a chicken soup style flavor. Pickles made from cabbage heads are tender and crisp.

Pickled mustard is a kind of mustard, we are familiar with mustard generally refers to leaf mustard, such as nine mustard, mustard seed, pig blood mustard, bean curd skin mustard, etc., but there are two kinds of mustard varieties, one is edible abnormal stem, that is,"pickled mustard," there is also a kind of edible abnormal bud, such as children's vegetables on the market.

Pickled mustard tuber is a kind of processed product of stem mustard. It is crisp and tender in texture, delicious in flavor, rich in nutrition and has a special flavor. It is mainly produced in Chongqing and Zhejiang.

Key Points of Transplanting and Seed Retention of Pickled Vegetable

Five Points of Transplanting Pickled Vegetable

First, the base fertilizer should be applied deeply: some farmers apply the base fertilizer only after raking before transplanting pickled mustard tuber, so that the fertilizer is easily lost through sun and rain exposure in the air, greatly reducing the utilization rate of fertilizer; therefore, the base fertilizer of pickled mustard tuber should be applied before soil preparation after ploughing.

The second is to prevent diseases and insect pests once in the seedling field one day before the seedling of pickled mustard tuber, so as to ensure that the seedlings are moved into the field healthily.

Third, the seedling land should be wetted before seedling raising: only in this way can the pickled vegetable seedlings be less damaged root system and improve the survival rate of transplanting.

Fourth, the density should be reduced: according to the investigation of agricultural technicians, the transplanting density of most farmers is high, and the most suitable planting density of pickled mustard is 2 - 22,000 plants, that is, the plant spacing is 12 cm and the row spacing is 25 cm.

Fifthly, apply fixed root fertilizer immediately after transplanting: apply fixed root fertilizer immediately to the pickled mustard seedlings transplanted on the same day to ensure that the whole seedlings are strong after transplanting.

In order to ensure the excellent seed quality of pickled mustard tuber, attention should be paid to the following four aspects when retaining seeds.

Get rid of the bad and the bad.

Only the plants with good head shape, characteristics of the variety, strong growth, no diseases and insect pests, and consistent bolting were retained in the reserved land. All miscellaneous and inferior plants that do not meet this standard shall be eliminated.

carry out topping

10--15 days after flowering, remove the tips of the main inflorescence and all branches, and no longer let it continue to bloom, so that nutrients can be concentrated to supply the remaining siliques, ensuring that the siliques are well developed and the grains are large and heavy. Topping seed plants is an economic and effective measure to increase yield.

pest control

To control aphid-based pests (and virus disease), the pesticide can be sprayed with 15 grams of imidacloprid per mu and water.

timely harvesting

When the middle and lower parts of the plant turn yellow and the seeds are brown, they can be harvested together with branches, bundled into bundles, placed in a cool and ventilated place, dried and threshed. After threshing, the seeds should be covered with paper or cloth and dried. It should not be exposed to the sun.
