The invention relates to a method for growing seedlings of pomelos. The method includes sequential steps of sowing seeds and cultivating rootstock; digging field planting pits; planting the rootstock seedlings in fields; carrying out grafting management. The method has the advantages that the method is high in pollination efficiency and seed collection quantity, early in seed collection time and good in stock-scion grafting compatibility, and the rootstock is high in disease resistance; shortcomings of low winter and spring temperatures, short illumination time, great humidity variation and insufficient soil nutrient supply can be overcome, and growth of the rootstock seedlings can be greatly accelerated; seedling recovering stages due to damage to root systems can be omitted, the growth density of plants is obviously lowered after the plants are planted in the fields, accordingly, tree growing spaces can be greatly increased, utilization of illumination, water and nutrients can be greatly improved, a large quantity of nutrition can be accumulated in trees, tips of branches can grow fast, trunk diameters and thicknesses can be quickly increased, grafting can be carried out in advance, tree forms can be formed early after the trees are grafted, flowering and fruit bearing can be shifted to an earlier time, and economic benefits can be realized quickly; organic fertilizers contain comprehensive and balanced nutritional components, accordingly, growth and development requirements of the pomelos can be met, and growth of the pomelos can be accelerated.

The invention discloses a walnut nutrition cup seedling culture method. The walnut nutrition cup seedling culture method includes the steps of variety selection, stock seed processing, walnut nutrition cup preparation, sowing and seedling raising, nutrition cup seedling transplanting, nutrition cup seedling trunk cutting, and grafting. By means of nutrition cup seedling culture, an excellent and low-cost matrix is selected, existing nutrient soil and moisture in a nutrition cup are fully utilized by nursery stocks, and direct growth can be achieved without seedling recovering. Compared with bare-rooted seedling afforestation, the method has the characteristics and advantages of being resistant to drought and poor soil and high in afforestation survival rate, nursery stock roots especially tap root systems can be kept complete and can not be damaged, and the afforestation survival rate is high.

The invention discloses a method for breeding small-seeded pumpkin rootstock varieties, and belongs to the field of melon rootstock breeding. The specific steps of the breeding method are as follows: study the genetic law of pumpkin seed size and the number of seeds of a single melon according to the isolated population, and select parents and matching combinations according to the genetic law. The male parent is a stable inbred line selected from the rootstock variety "Huofenghuang" introduced from Shandong after 7 generations of self-crossing. This is a stable inbred line selected from the fertile plants of Shanxi melon grafted rootstock variety "Snow White" after 6 generations of selfing. It is characterized by round fruit, well-developed taproot, orange peel, early maturity, high temperature resistance and low temperature resistance. Strong; obtained from the above male and female parent crosses. The obtained varieties have small cotyledons, are suitable for seedling cultivation in 50-hole plug trays, are highly resistant to watermelon wilt, have neat germination, are not easy to grow excessively, have a long grafting period, are convenient for grafting, and have a high grafting survival rate.

The invention discloses a method for culturing an ornamental fruit rugosa tree and belongs to the field of garden plant culturing. The method for culturing the ornamental fruit rugosa tree comprises the steps that a rose is cultured into a forming stock, an ornamental fruit rugosa scion is grafted, and management after grafting is carried out; or a rose is cultured into the forming stock, mixing grafting of an ornamental fruit rugosa scion and an ornamental flower rugosa scion is carried out, and management after grafting is carried out. According to the method, the stock and scion grafting combination, the grafting period and the fixed trunk height of the stock are optimized, and it is found that the best grafting compatibility is achieved with the American floribunda no-thorn rose as the stock and a pink single-lobe rose; the grafting survival rate is the highest when grafting is carried out in the middle ten days of March; and the ornamental effect is the best when the fixed trunk height of the stock ranges from 85 cm to 95 cm. The ornamental fruit rugosa tree cultured through the method has an independent trunk, the tree shape is full and attractive, and both fruits and flowers can be ornamented; due to the fact that the ornamental fruit rugosa and the ornamental flower rugosa are grafted on the same stock, the flower ornamental effect can be further improved, the bloom time can be prolonged, and the ornamental value and the commercial value of the ornamental fruit rugosa tree can be improved.

The invention discloses a cultivation method for improving cold resistance of an improved peach variety. The problems of shortage of improved peach variety in Hexi district in Gansu province and difficulty of large-scale development of peaches are solved. The method comprises the following steps of: A selecting stocks, namely selecting local seedling Gansu wild peach stocks; B, building a stock garden, namely adopting 2-3 perennial wild peach stock seedlings, digging planting holes according to the planting space of 2*4m, laying a crop straw layer with the thickness of 15cm at the bottoms of the holes, uniformly mixing and filling the holes through surface soil, sand and thoroughly decomposed sheep manure, watering, settling and planting; C, grafting, namely taking developmental branches of the improved peach variety which have full growth and full eyes as scions, performing multi-branch top grafting on 20, June to 10, August by employing a T-shaped budding method, and finishing grafting of 6-10 buds; D, managing after grafting; and E, trimming. The local seedling Gansu wild peach stocks are selected, the cultivation method is high in adaptability and high in grafting compatibility, and the fruiting year limit is prolonged; and moreover, the cold resistance of the improved peach variety is greatly improved, and the aim of safely overwintering the exposed improved peach variety is fulfilled.

The method for breeding special hybrid rootstocks for the prevention and treatment of facility watermelon wilt disclosed by the present invention is to select local long gourd varieties in Zhejiang, separate and purify them through at least three generations of self-crossing, identify and screen out the plants that grow steadily under low temperature and low light conditions, and have strong low temperature resistance The inbred line CH-1 was used as the female parent, and the inbred line YH-6 with strong low temperature resistance, drought tolerance and heat resistance was identified and screened as the male parent. A first-generation hybrid was prepared and named "Huluzhen No. 1". The hybrid rootstock selected by the method of the present invention meets the breeding objective, is highly resistant to watermelon wilt, has good grafting affinity with watermelon, and has strong symbiotic affinity, and is suitable for continuous cropping watermelon grafting and cultivation in the south with low temperature and rain in the early stage and high temperature in the later stage, and under facility cultivation conditions Good moisture and heat resistance, stable growth under low temperature and weak light, easy to set fruit, can effectively prevent and control watermelon wilt, increase watermelon production and improve quality.
