  • Root sucker transplanting method for vegetative propagation of Schisandra chinensis

    In cultivation gardens, Schisandra chinensis trees over 3 years old can produce large numbers of horizontal rhizomes, distributed in the soil layer 5-15 cm below the surface. From May to July, adventitious buds on the horizontal rhizomes sprout and produce large numbers of root suckers. When the young shoots are 10-15 cm tall, dig out the horizontal rhizomes, cut off the "seedlings" with root systems using scissors, and plant them in the prepared nursery field at a spacing of 10 cm x 20 cm, as shown in Figure 3-6. If planting on a sunny day

  • Causes of Cotton Excessive Vegetative Growth and Control Methods

    The phenomenon in which vegetative organs such as stems, branches and leaves of the cotton plant grow excessively, causing an imbalance between vegetative growth and reproductive growth, is called excessive vegetative growth, commonly known as "runaway growth." After cotton squaring, vegetative growth and reproductive growth proceed simultaneously. If vegetative growth is too rapid and reproductive growth is inhibited, it will cause shedding of squares and bolls, and in severe cases, no bolls will set. Causes of excessive vegetative growth: mainly excessive application of fertilizer and water. From squaring to the early flowering stage is the period of fastest vegetative growth in the entire life of cotton. If nitrogen fertilizer is supplied in excess, it will cause an imbalance in the carbon-to-nitrogen metabolism ratio

  • How to prevent and control excessive vegetative growth in cotton? A detailed guide to practical techniques

    At present, cotton has entered the squaring stage, and preventing excessive vegetative growth in cotton must begin now. So-called excessive vegetative growth means the cotton has lost its normal reproductive function, that is, it only flowers without setting bolls, or it flowers heavily but sets few bolls. The causes are first climatic factors, second the blind and random introduction of cotton varieties, and third cultivation methods that do not match climate change. According to records, when the temperature exceeds 35°C, pollen development becomes abnormal and normal pollination cannot occur; while sustained drought intensifies the shedding of squares and bolls. In addition, in mid-August some cotton areas experience

  • Detailed Explanation of Methods for Storage and Preservation of Tea Plant Vegetative Propagules

    Direct field preservation of tea plant vegetative propagules requires a large amount of land and labor, so long-term preservation techniques for tea roots, seedlings, seeds and pollen have been studied. Root preservation involves sterilizing the lignified roots before spring sprouting, storing them together with sterilized semi-dry soil or sphagnum moss in plastic bags, and placing them in an environment of 1-5°C. After 7 years of storage, the occurrence of adventitious buds can reach up to 70%. Stored at 1°C for 6 years, the roots can still regenerate. Under low-temperature storage conditions, the consumption of carbohydrates in root tissues

  • Nursery Management Techniques for Vegetative Cutting Propagation of Tea Plants

    (1) Watering On sunny days, within 20 days after cuttings are inserted, water once in the morning and once in the evening each day to keep the soil moist; from day 20 to 60, water once a day, and pay attention to drainage on rainy days. (2) Fertilizing Fertilizing can begin 60 days after cuttings are inserted, once every 7-10 days, then changed to once every 15 days after 2 months. In the third month after cuttings are inserted, apply 1.5 kg of urea per mu each time; from the fifth month onward, apply 2-2.5 kg of urea each time, and each application per mu must be diluted with 12 dan of water; the fertilizer solution should be mixed evenly to avoid damaging roots and leaves. (3) Removing shade material Tea

  • Detailed Explanation of Key Techniques for Vegetative Cutting Propagation of Tea Plants

    1. Site Selection The nursery should be chosen in paddy fields or hillside plots with convenient irrigation and drainage. Plots where tobacco, hemp, tuber crops, or vegetables were previously grown should not be used as nurseries to avoid root-knot nematodes. 2. Seedbed Preparation After the nursery site is deep-plowed and the soil is harrowed and broken up, seedbeds are made 10-15 cm high and 100 cm wide, oriented east-west, with length determined by the terrain. The ditch between seedbeds is 40-50 cm wide. Apply 1-2 tons of decomposed stable manure per mu, mix thoroughly with the seedbed soil and level it, then spread a layer of 5

  • What to Do About Excessive Vegetative Growth of Straw Mushroom Mycelium? Detailed Control Methods

    During the mycelial growth stage of straw mushroom, a large amount of white fluffy aerial mycelium forms on the surface of the substrate, sometimes even growing into a white layer of mycelial mat, which delays fruiting and leads to low yields; the cause is excessively high temperature inside the compost heap. Control methods: after inoculating straw mushroom, regularly uncover the plastic film to ventilate and lower both temperature and humidity, and do not cover with too thick a layer of straw, so as to encourage the mycelium to grow into the substrate.
