Mustard Main Cultivation Techniques

Mustard Main Cultivation Techniques

(I) Mustard seedlings in the sowing season are planted with young plantlets such as Brassica napus, which have high heat resistance and short growth period. They are suitable for sowing in April-September, and adopt the live broadcast method; Such as packaged mustard, generally using seedling transplantation methods, planting in the fall, August to October sowing is more appropriate.
(b) Sow seedling nursery beds should be neat and smooth. Give full use of farmyard manure. The amount of seeds used for direct seeding is 300 grams; for transplanting seedlings, 25 grams to 30 grams are needed per acre, and the seedling period is 25 days to 30 days. During the nursery period, it is necessary to prevent the aphids from being harmed.
(C) the colonization of leaf mustard to adapt to a wider range of soil, but mustard cabbage to win high yield, to choose the former as the sandy loam of rice, and sufficient base fertilizer, hit hole planting, the second line planting, plant spacing 40 cm ~ 50 Centimeter, more mature species to be properly sparse. Mustard roots are slow, and should be transplanted with as much soil as possible and avoid rooting, and the roots should not be bent into the soil in order to increase the survival rate.
(D) Daejeon management Leaf mustard is a vegetable served by leaves, topdressing with nitrogen fertilizers. Heat-resistant, early-maturing varieties such as Brassica napus, use available nitrogen fertilizer to ensure rapid growth of plants, available urea 20 kg to 25 kg per mu, used 3 to 4 times. In addition to nitrogen fertilizer, it must be applied with appropriate amount of phosphorus and Hefei. In the early stage, 10 kg of urea should be applied in order to promote the full growth and solidification of the leaf ball; the water supply should be uniform and the soil should be avoided during the filling period. Diseases caused by wet, heavy fertilizer before plant closure line; do not apply fertilizer after the line is closed, and try to avoid the water poured on the leaf ball; can be used in the late growth furrow irrigation, dry weather every 2 days to 3 days furrow irrigation once to maintain a moist state. For the harvested leaf bulbs that are harvested for processing, the moisture supply is controlled 20 days before harvest to improve the quality of processed products.
(5) Major pest and disease control
(1) Clubroot disease mainly occurs in the roots of Brassica juncea, causing the roots to form a tumour. The tumours of the major roots are large. The tumours of the lateral roots are smaller and the roots of the asparagus are smaller. The rotten bacteria are invaded by the saprophytic fungi in the late stage of the disease and cause rotting odor. The roots of the affected plants absorb water, nutrients are blocked, the aboveground parts grow slowly and the plants are dwarfed. In the early stage of the disease, the performance of the disease retreats during the day and recovers sooner or later. After that, the leaves gradually turn yellow until they die. The disease is prone to disease in the soil that is acidic and continuous. Control methods: Before selection, the plots were planted as rice or non-cruciferous vegetables; watered with 50% carbendazim WP 600 times.
(2) Virus disease, soft rot disease, yellow striped flea beetle, aphid, etc. can be controlled by reference to the control methods of other vegetables.
(6) The heat-resistance and early maturing species of the harvest leaf mustard can be harvested and marketed on multiple occasions; some large meat mustard varieties have a longer growth period and a longer harvest period. According to the maturity and weather conditions, the mustard must be harvested on sunny days when the leaves are fully grown without popping; they are cut at the base of the plants at the time of harvest, and are left in the fields for a period of time. Then concentrate on the processing field.
